1.1 KeyStone Architecture
TI’s KeyStone Multicore Architecture provides a high performance structure for integrating RISC and DSP cores
with application specific coprocessors and I/O. KeyStone is the first of its kind that provides adequate internal
bandwidth for nonblocking access to all processing cores, peripherals, coprocessors, and I/O. This is achieved with
four main hardware elements: Multicore Navigator, TeraNet, Multicore Shared Memory Controller, and
HyperLink.
Multicore Navigator is an innovative packet-based manager that controls 8192 queues. When tasks are allocated to
the queues, Multicore Navigator provides hardware-accelerated dispatch that directs tasks to the appropriate
available hardware. The packet-based system on a chip (SoC) uses the two Tbps capacity of the TeraNet switched
central resource to move packets. The Multicore Shared Memory Controller enables processing cores to access
shared memory directly without drawing from TeraNet’s capacity, so packet movement cannot be blocked by
memory access.
HyperLink provides a 50-Gbaud chip-level interconnect that allows SoCs to work in tandem. Its low-protocol
overhead and high throughput make HyperLink an ideal interface for chip-to-chip interconnections. Working with
Multicore Navigator, HyperLink dispatches tasks to tandem devices transparently and executes tasks as if they are
running on local resources.
1.2 Device Description
The TMS320C6671 DSP is a highest-performance fixed/floating-point single-core DSP that is based on TI's
KeyStone multicore architecture. It is pin-for-pin compatible with the TMS320C6678 / 6674 / 6672 multicore
high-performance DSPs. Incorporating the new and innovative C66x DSP core, this device can run at a core speed
of up to 1.25 GHz. For developers of a broad range of applications, such as mission critical, medical imaging, test
and automation, and other applications requiring high performance, TI's TMS320C6671 DSP offers a platform that
is power-efficient and easy to use. In addition, it is fully backward compatible with all existing C6000 family of fixed
and floating point DSPs.
TI's KeyStone architecture provides a programmable platform integrating various subsystems (C66x cores, memory
subsystem, peripherals, and accelerators) and uses several innovative components and techniques to maximize
intra-device and inter-device communication that allows the various DSP resources to operate efficiently and
seamlessly. Central to this architecture are key components such as Multicore Navigator that allows for efficient data
management between the various device components. The TeraNet is a non-blocking switch fabric enabling fast and
contention-free internal data movement. The multicore shared memory controller allows access to shared and
external memory directly without drawing from switch fabric capacity.
For fixed-point use, the C66x core has 4× the multiply accumulate (MAC) capability of C64x+ cores. In addition,
the C66x core integrates floating point capability and the per core raw computational performance is an
industry-leading 32 MACS/cycle and 16 flops/cycle. It can execute 8 single precision floating point MAC operations
per cycle and can perform double- and mixed-precision operations and is IEEE754 compliant. The C66x core
incorporates 90 new instructions (compared to the C64x+ core) targeted for floating point and vector math oriented
processing. These enhancements yield sizeable performance improvements in popular DSP kernels used in signal
processing, mathematical, and image acquisition functions. The C66x core is backwards code compatible with TI's
previous generation C6000 fixed and floating point DSP cores, ensuring software portability and shortened software
development cycles for applications migrating to faster hardware.
The C6671 DSP integrates a large amount of on-chip memory. In addition to 32KB of L1 program and data cache,
there is 512KB of dedicated memory that can be configured as mapped RAM or cache. The device also integrates
4096KB of Multicore Shared Memory that can be used as a shared L2 SRAM and/or shared L3 SRAM. All L2
memories incorporate error detection and error correction. For fast access to external memory, this device includes
a 64-bit DDR-3 external memory interface (EMIF) running at 1600 MHz and has ECC DRAM support.

2.2 DSP Core Description
The C66x Digital Signal Processor (DSP) extends the performance of the C64x+ and C674x DSPs through
enhancements and new features. Many of the new features target increased performance for vector processing. The
C64x+ and C674x DSPs support 2-way SIMD operations for 16-bit data and 4-way SIMD operations for 8-bit data.
On the C66x DSP, the vector processing capability is improved by extending the width of the SIMD instructions.
C66x DSPs can execute instructions that operate on 128-bit vectors. For example the QMPY32 instruction is able to
perform the element-to-element multiplication between two vectors of four 32-bit data each. The C66x DSP also
supports SIMD for floating-point operations. Improved vector processing capability (each instruction can process
multiple data in parallel) combined with the natural instruction level parallelism of C6000 architecture (e.g
execution of up to 8 instructions per cycle) results in a very high level of parallelism that can be exploited by DSP
programmers through the use of TI's optimized C/C++ compiler.
The C66x DSP consists of eight functional units, two register files, and two data paths as shown in Figure 2-1. The
two general-purpose register files (A and B) each contain 32 32-bit registers for a total of 64 registers. The
general-purpose registers can be used for data or can be data address pointers. The data types supported include
packed 8-bit data, packed 16-bit data, 32-bit data, 40-bit data, and 64-bit data. Multiplies also support 128-bit data.
40-bit-long or 64-bit-long values are stored in register pairs, with the 32 LSBs of data placed in an even register and
the remaining 8 or 32 MSBs in the next upper register (which is always an odd-numbered register). 128-bit data
values are stored in register quadruplets, with the 32 LSBs of data placed in a register that is a multiple of 4 and the
remaining 96 MSBs in the next 3 upper registers.
The eight functional units (.M1, .L1, .D1, .S1, .M2, .L2, .D2, and .S2) are each capable of executing one instruction
every clock cycle. The .M functional units perform all multiply operations. The .S and .L units perform a general set
of arithmetic, logical, and branch functions. The .D units primarily load data from memory to the register file and
store results from the register file into memory.
Each C66x .M unit can perform one of the following fixed-point operations each clock cycle: four 32 × 32 bit
multiplies, sixteen 16 × 16 bit multiplies, four 16 × 32 bit multiplies, four 8 × 8 bit multiplies, four 8 × 8 bit multiplies
with add operations, and four 16 × 16 multiplies with add/subtract capabilities. There is also support for Galois field
multiplication for 8-bit and 32-bit data. Many communications algorithms such as FFTs and modems require
complex multiplication. Each C66x .M unit can perform one 16 × 16 bit complex multiply with or without rounding
capabilities, two 16 × 16 bit complex multiplies with rounding capability, and a 32 × 32 bit complex multiply with
rounding capability. The C66x can also perform two 16 × 16 bit and one 32 × 32 bit complex multiply instructions
that multiply a complex number with a complex conjugate of another number with rounding capability.
Communication signal processing also requires an extensive use of matrix operations. Each C66x .M unit is capable
of multiplying a [1 × 2] complex vector by a [2 × 2] complex matrix per cycle with or without rounding capability.
A version also exists allowing multiplication of the conjugate of a [1 × 2] vector with a [2 × 2] complex matrix.
Each C66x .M unit also includes IEEE floating-point multiplication operations from the C674x DSP, which includes
one single-precision multiply each cycle and one double-precision multiply every 4 cycles. There is also a
mixed-precision multiply that allows multiplication of a single-precision value by a double-precision value and an
operation allowing multiplication of two single-precision numbers resulting in a double-precision number. The
C66x DSP improves the performance over the C674x double-precision multiplies by adding a instruction allowing
one double-precision multiply per cycle and also reduces the number of delay slots from 10 down to 4. Each C66x
.M unit can also perform one the following floating-point operations each clock cycle: one, two, or four
single-precision multiplies or a complex single-precision multiply.
The .L and .S units can now support up to 64-bit operands. This allows for new versions of many of the arithmetic,
logical, and data packing instructions to allow for more parallel operations per cycle. Additional instructions were
added yielding performance enhancements of the floating point addition and subtraction instructions, including the
ability to perform one double precision addition or subtraction per cycle. Conversion to/from integer and
single-precision values can now be done on both .L and .S units on the C66x. Also, by taking advantage of the larger
16

Fixed and Floating-Point Digital Signal Processor
SPRS756A—July 2011
www.ti.com
operands, instructions were also added to double the number of these conversions that can be done. The .L unit also
has additional instructions for logical AND and OR instructions, as well as, 90 degree or 270 degree rotation of
complex numbers (up to two per cycle). Instructions have also been added that allow for the computing the
conjugate of a complex number.
The MFENCE instruction is a new instruction introduced on the C66x DSP. This instruction will create a DSP stall
until the completion of all the DSP-triggered memory transactions, including:
•
•
•
•
•
•
Cache line fills
Writes from L1D to L2 or from the CorePac to MSMC and/or other system endpoints
Victim write backs
Block or global coherence operations
Cache mode changes
Outstanding XMC prefetch requests
This is useful as a simple mechanism for programs to wait for these requests to reach their endpoint. It also provides
ordering guarantees for writes arriving at a single endpoint via multiple paths, multiprocessor algorithms that
depend on ordering, and manual coherence operations.

2.4 Boot Sequence
The boot sequence is a process by which the DSP's internal memory is loaded with program and data sections. The
DSP's internal registers are programmed with predetermined values. The boot sequence is started automatically
after each power-on reset, warm reset, and system reset. A local reset to the C66x CorePac should not affect the state
of the hardware boot controller on the device. For more details on the initiators of the resets, see section 7.5 ‘‘Reset
Controller’’ on page 112.
The C6671 supports several boot processes that begins execution at the ROM base address, which contains the
bootloader code necessary to support various device boot modes. The boot processes are software-driven and use
the BOOTMODE[12:0] device configuration inputs to determine the software configuration that must be
completed. For more details on Boot Sequence see the Bootloader for the C66x DSP User Guide (literature number
SPRUGY5).
2.5 Boot Modes Supported and PLL Settings
The device supports several boot processes, which leverage the internal boot ROM. Most boot processes are software
driven, using the BOOTMODE[3:0] device configuration inputs to determine the software configuration that must
be completed. From a hardware perspective, there are two possible boot modes:
•
Public ROM Boot - C66x CorePac0is released from reset and begins executing from the L3 ROM base address.
After performing the boot process (e.g., from I2C ROM, Ethernet, or RapidIO), C66x CorePac0 then begins
execution from the provided boot entry point. See the Bootloader for the C66x DSP User Guide (literature
number SPRUGY5) for more details.

•
Secure ROM Boot - On secure devices, the C66x CorePac0is released from reset and begin executing from
secure ROM. Software in the secure ROM will free up internal RAM pages, after which the C66x CorePac
initiates the boot process. The C66x CorePac0 performs any authentication and decryption required on the
bootloaded image prior to beginning execution.
The boot process performed by the C66x CorePac0 in public ROM boot and secure ROM boot are determined by
the BOOTMODE[12:0] value in the DEVSTAT register. The C66x CorePac0 reads this value, and then executes the
associated boot process in software. Figure 2-2 shows the bits associated with BOOTMODE[12:0].

2.5.2.5.1 I2C Master Mode
In master mode, the I2C device configuration uses ten bits of device configuration instead of seven as used in other
boot modes. In this mode, the device will make the initial read of the I2C EEPROM while the PLL is in bypass mode.
The initial read will contain the desired clock multiplier, which will be set up prior to any subsequent reads.

2.5.3 PLL Boot Configuration Settings
The PLL default settings are determined by the BOOTMODE[12:10] bits. Table 2-13 shows settings for various
input clock frequencies. OUTPUT_DIVIDE is the value of the field of SECCTL[22:19]. This will set the PLL to the
maximum clock setting for the device (with OUTPUT_DIVIDE=2, by default).
CLK = CLKIN × (PLLM+1) ÷ (OUTPUT_DIVIDE × (PLLD+1))
The configuration for the PASS PLL is also shown. The PASS PLL is configured with these values only if the Ethernet
boot mode is selected with the input clock set to match the main PLL clock (not the SGMII SerDes clock). See
Table 2-3 for details on configuring Ethernet boot mode. The output from the PASS PLL goes through an on-chip
divider to reduce the operating frequency before reaching the NETCP. The PASS PLL generates 1050 MHz, and after
the chip divider (=3), feeds 350 MHz to the NETCP.
See section 7.6 ‘‘Main PLL and PLL Controller’’ on page 117 for further details

2.8 Terminal Functions
The terminal functions table (Table 2-15) identifies the external signal names, the associated pin (ball) numbers, the
pin type (I, O/Z, or I/O/Z), whether the pin has any internal pullup/pulldown resistors, and gives functional pin
descriptions. This table is arranged by function. The power terminal functions table (Table 2-16) lists the various
power supply pins and ground pins and gives functional pin descriptions. Table 2-17 shows all pins arranged by
signal name. Table 2-18 shows all pins arranged by ball number.
There are 17 pins that have a secondary function as well as a primary function. The secondary function is indicated
with a dagger (†).
For more detailed information on device configuration, peripheral selection, multiplexed/shared pins, and
pullup/pulldown resistors, see section 3.4 ‘‘Pullup/Pulldown Resistors’’ on page 80.
Use the symbol definitions in Table 2-14 when reading Table 2-15.

Internal 100-μA pulldown or pullup is provided for this terminal. In most systems, a 1-kΩ resistor can
be used to oppose the IPD/IPU. For more detailed information on pulldown/pullup resistors and
situations in which external pulldown/pullup resistors are required, see Hardware Design Guide for
KeyStone Devices (literature number SPRABI2).

2.9.2 Device Support
2.9.2.1 Device and Development-Support Tool Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all DSP devices
and support tools. Each DSP commercial family member has one of three prefixes: TMX, TMP, or TMS (e.g.,
TMX320CMH). Texas Instruments recommends two of three possible prefix designators for its support tools:
TMDX and TMDS. These prefixes represent evolutionary stages of product development from engineering
prototypes (TMX/TMDX) through fully qualified production devices/tools (TMS/TMDS).
Device development evolutionary flow:
•
•
TMX: Experimental device that is not necessarily representative of the final device's electrical specifications
TMP: Final silicon die that conforms to the device's electrical specifications but has not completed quality and
reliability verification
•
TMS: Fully qualified production device
Support tool development evolutionary flow:
•
TMDX: Development-support product that has not yet completed Texas Instruments internal qualification
testing.
•
TMDS: Fully qualified development-support product
TMX and TMP devices and TMDX development-support tools are shipped with the following disclaimer:
"Developmental product is intended for internal evaluation purposes."
TMS devices and TMDS development-support tools have been characterized fully, and the quality and reliability of
the device have been demonstrated fully. TI's standard warranty applies.
Predictions show that prototype devices (TMX or TMP) have a greater failure rate than the standard production
devices. Texas Instruments recommends that these devices not be used in any production system because their
expected end-use failure rate still is undefined. Only qualified production devices are to be used.

3 Device Configuration
On the TMS320C6671 device, certain device configurations like boot mode and endianess, are selected at device
power-on reset. The status of the peripherals (enabled/disabled) is determined after device power-on reset.
3.1 Device Configuration at Device Reset
Table 3-1 describes the device configuration pins. The logic level is latched at power-on reset to determine the device
configuration. The logic level on the device configuration pins can be set by using external pullup/pulldown resistors
or by using some control device (e.g., FPGA/CPLD) to intelligently drive these pins. When using a control device,
care should be taken to ensure there is no contention on the lines when the device is out of reset. The device
configuration pins are sampled during power-on reset and are driven after the reset is removed. To avoid
contention, the control device must stop driving the device configuration pins of the DSP.And when driving by a
control device, the control device must be fully powered and out of reset itself and driving the pins before the DSP
can be taken out of reset.
Also, please note that most of the device configuration pins are shared with other function pins
(LENDIAN/GPIO[0], BOOTMODE[12:0]/GPIO[13:1], PCIESSMODE[1:0]/GPIO[15:14] and PCIESSEN/TIMI0),
some time must be given following the rising edge of reset in order to drive these device configuration input pins
before they assume an output state (those GPIO pins should not become outputs during boot). Another caution that
needs to be noted is that systems using TIMI0 (pin shared with PCIESSEN) as a clock input must assure that the
clock itself is disabled from the input until after reset is released and a control device is no longer driving that input.
Note—If a configuration pin must be routed out from the device and it is not driven (Hi-Z state), the internal
pullup/pulldown (IPU/IPD) resistor should not be relied upon. TI recommends the use of an external
pullup/pulldown resistor. For more detailed information on pullup/pulldown resistors and situations in
which external pullup/pulldown resistors are required, see Section 3.4 ‘‘Pullup/Pulldown Resistors’’ on
page 80.

3.2 Peripheral Selection After Device Reset
Several of the peripherals on the TMS320C6671 are controlled by the Power Sleep Controller (PSC). By default, the
PCIe, SRIO, and HyperLink are held in reset and clock-gated. The memories in these modules are also in a
low-leakage sleep mode. Software is required to turn these memories on. The software enables the modules (turns
on clocks and de-asserts reset) before these modules can be used.
If one of the above modules is used in the selected ROM boot mode, the ROM code will automatically enable the
module.
All other modules come up enabled by default and there is no special software sequence to enable. For more detailed
information on the PSC usage, see the Power Sleep Controller (PSC) for KeyStone Devices User Guide (literature
number SPRUGV4).
3.3 Device State Control Registers
The TMS320C6671 device has a set of registers that are used to provide the status or configure certain parts of its
peripherals. These registers are shown in Table 3-2.

3.3.4 Kicker Mechanism (KICK0 and KICK1) Register
The Bootcfg module contains a kicker mechanism to prevent any spurious writes from changing any of the Bootcfg
MMR values. When the kicker is locked (which it is initially after power on reset) none of the Bootcfg MMRs are
writable (they are only readable). This mechanism requires two MMR writes to the KICK0 and KICK1 registers with
exact data values before the kicker lock mechanism is un-locked. See Table 3-2 ‘‘Device State Control Registers’’ on
page 65 for the address location. Once released then all the Bootcfg MMRs having “write” permissions are writable
(the read only MMRs are still read only). The first KICK0 data is 0x83e70b13. The second KICK1 data is 0x95a4f1e0.
Writing any other data value to either of these kick MMRs will lock the kicker mechanism and block any writes to
Bootcfg MMRs.
The kicker mechanism is unlocked by the ROM code. Do not write any other different values afterward to these
registers because that will lock the kicker mechanism and block any writes to Bootcfg registers.

LRESETNMI PIN Status Clear Register is shown.
3.3.7 Reset Status (RESET_STAT) Register
The reset status register (RESET_STAT) captures the status of Local reset (LRx) for each of the cores and also the
global device reset (GR). Software can use this information to take different device initialization steps, if desired.
•
In case of Local reset: The LRx bits are written as 1 and GR bit is written as 0 only when the CorePac receives
an local reset without receiving a global reset.
•
In case of Global reset: The LRx bits are written as 0 and GR bit is written as 1 only when a global reset is
asserted.
The Reset Status Register is shown in Figure 3-5 and described in Table 3-7.

The BCx bit indicates the boot complete status of the corresponding core. All BCx bits will be sticky bits — that is
they can be set only once by the software after device reset and they will be cleared to 0 on all device resets.
Boot ROM code will be implemented such that each core will set its corresponding BCx bit immediately before
branching to the predefined location in memory.
3.3.10 Power State Control (PWRSTATECTL) Register
The PWRSTATECTL register is controlled by the software to indicate the power-saving mode. ROM code reads this
register to differentiate between the various power saving modes. This register is cleared only by Power On Reset
and will survive all other device resets. See the Hardware Design Guide for KeyStone Devices in ‘‘Related
Documentation from Texas Instruments’’ on page 63 for more information. The Power State Control Register is
shown in Figure 3-8 and described in Table 3-10.

3.3.11 NMI Even Generation to CorePac (NMIGRx) Register
NMIGRx registers are used for generating NMI events to the corresponding CorePac. The C6671 has
one NMIGRx register (NMIGR0). The NMIGR0 register generates an NMI event to CorePac0. Writing a 1 to the
NMIG field generates a NMI pulse. Writing a 0 has no effect and reads return 0 and have no other effect. The NMI

3.3.12 IPC Generation (IPCGRx) Registers
IPCGRx are the IPC interrupt generation registers to facilitate inter CorePac interrupts.
The C6671 has one IPCGRx register (IPCGR0). This register can be used by external hosts or CorePacs to generate
interrupts to other CorePacs. A write of 1 to IPCG field of IPCGRx register will generate an interrupt pulse to
CorePac0.
These registers also provide a Source ID facility by which up to 28 different sources of interrupts can be identified.
Allocation of source bits to source processor and meaning is entirely based on software convention. The register field
descriptions are given in the following tables. Virtually anything can be a source for these registers as this is
completely controlled by software. Any master that has access to BOOTCFG module space can write to these
registers. The IPC Generation Register is shown in Figure 3-10 and described in Table 3-12.

3.3.13 IPC Acknowledgement (IPCARx) Registers
IPCARx are the IPC interrupt-acknowledgement registers to facilitate inter-CorePac core interrupts.
The C6671 has one IPCARx register (IPCAR0). This register also provides a Source ID facility by which up to 28
different sources of interrupts can be identified. Allocation of source bits to source processor and meaning is entirely
based on software convention. The register field descriptions are shown in the following tables. Virtually anything
can be a source for these registers as this is completely controlled by software. Any master that has access to
BOOTCFG module space can write to these registers. The IPC Acknowledgement Register is shown in Figure 3-11
and described in Table 3-13.

The host interrupt output pulse should be stretched. It should be asserted for 4 bootcfg clock cycles (DSP/6) followed
by a deassertion of 4 bootcfg clock cycles. Generating the pulse will result in 8 DSP/6 cycle pulse blocking window.
Write to IPCGRH with IPCG bit (bit 0) set will only generate a pulse if they are beyond 8 DSP/6 cycle period. The
IPC Generation Host Register is shown in Figure 3-12 and described in Table 3-14.

3.4 Pullup/Pulldown Resistors
Proper board design should ensure that input pins to the device always be at a valid logic level and not floating. This
may be achieved via pullup/pulldown resistors. The device features internal pullup (IPU) and internal pulldown
(IPD) resistors on most pins to eliminate the need, unless otherwise noted, for external pullup/pulldown resistors.
An external pullup/pulldown resistor needs to be used in the following situations:
•
Device Configuration Pins: If the pin is both routed out and are not driven (in Hi-Z state), an external
pullup/pulldown resistor must be used, even if the IPU/IPD matches the desired value/state.
•
Other Input Pins: If the IPU/IPD does not match the desired value/state, use an external pullup/pulldown
resistor to pull the signal to the opposite rail.
For the device configuration pins (listed in Table 3-1), if they are both routed out and are not driven (in Hi-Z state),
it is strongly recommended that an external pullup/pulldown resistor be implemented. Although, internal
pullup/pulldown resistors exist on these pins and they may match the desired configuration value, providing
external connectivity can help ensure that valid logic levels are latched on these device configuration pins. In
addition, applying external pullup/pulldown resistors on the device configuration pins adds convenience to the user
in debugging and flexibility in switching operating modes.
Tips for choosing an external pullup/pulldown resistor:
•
•
Consider the total amount of current that may pass through the pullup or pulldown resistor. Make sure to
include the leakage currents of all the devices connected to the net, as well as any internal pullup or pulldown
resistors.
Decide a target value for the net. For a pulldown resistor, this should be below the lowest VIL level of all inputs
connected to the net. For a pullup resistor, this should be above the highest VIH level of all inputs on the net.
A reasonable choice would be to target the VOL or VOH levels for the logic family of the limiting device; which,
by definition, have margin to the VIL and VIH levels.
•
•
Select a pullup/pulldown resistor with the largest possible value that can still ensure that the net will reach the
target pulled value when maximum current from all devices on the net is flowing through the resistor. The
current to be considered includes leakage current plus, any other internal and external pullup/pulldown
resistors on the net.
For bidirectional nets, there is an additional consideration that sets a lower limit on the resistance value of the
external resistor. Verify that the resistance is small enough that the weakest output buffer can drive the net to
the opposite logic level (including margin).
•
•
Remember to include tolerances when selecting the resistor value.
For pullup resistors, also remember to include tolerances on the DVDD rail.
For most systems:
•
A 1-kΩ resistor can be used to oppose the IPU/IPD while meeting the above criteria. Users should confirm this
resistor value is correct for their specific application.
•
A 20-kΩ resistor can be used to compliment the IPU/IPD on the device configuration pins while meeting the
above criteria. Users should confirm this resistor value is correct for their specific application.
For more detailed information on input current (II), and the low-level/high-level input voltages (VIL and VIH) for
the TMS320C6671 device, see Section 6.3 ‘‘Electrical Characteristics’’ on page 94.
To determine which pins on the device include internal pullup/pulldown resistors, see Table 2-15 ‘‘Terminal
Functions — Signals and Control by Function’’ on page 37.

4 System Interconnect
On the TMS320C6671 device, the C66x CorePac, the EDMA3 transfer controllers, and the system peripherals are
interconnected through two switch fabrics. The switch fabrics allow for low-latency, concurrent data transfers
between master peripherals and slave peripherals. The switch fabrics also allow for seamless arbitration between the
system masters when accessing system slaves.
4.1 Internal Buses, Bridges, and Switch Fabrics
Two types of buses exist in the device: data buses and configuration buses. Some peripherals have both a data bus
and a configuration bus interface, while others only have one type of interface. Furthermore, the bus interface width
and speed varies from peripheral to peripheral. Configuration buses are mainly used to access the register space of
a peripheral and the data buses are used mainly for data transfers. However, in some cases, the configuration bus is
also used to transfer data. Similarly, the data bus can also be used to access the register space of a peripheral.
The C66x CorePac, the EDMA3 traffic controllers, and the various system peripherals can be classified into two
categories: masters and slaves.
Masters are capable of initiating read and write transfers in the system and do not rely on the EDMA3 for their data
transfers. Slaves on the other hand rely on the masters to perform transfers to and from them. Examples of masters
include the EDMA3 traffic controllers, SRIO, and network coprocessor packet DMA. Examples of slaves include the
SPI, UART, and I2C.
The device contains two switch fabrics (the TeraNet) through which masters and slaves communicate. The data
switch fabric, known as the data switched central resource (SCR), is a high-throughput interconnect mainly used to
move data across the system (for more information, see Section 4.2 ‘‘Data Switch Fabric Connections’’). The data
SCR is further divided into two smaller SCRs. One connects very high speed masters to slaves via 256-bit data buses
running at a CPU/2 frequency. The other connects masters to slaves via 128-bit data buses running at a CPU/3
frequency. Peripherals that match the native bus width of the SCR it is connected to can connect directly to the data
SCR; other peripherals require a bridge.
The configuration switch fabric, also known as the configuration switch central resource (SCR), is mainly used to
access peripheral registers (for more information, see Section 4.3 ‘‘Configuration Switch Fabric’’). The
configuration SCR connects the C66x CorePac and masters on the data switch fabric to slaves via
32-bit configuration buses running at a CPU/3 frequency. As with the data SCR, some peripherals require the use of
a bridge to interface to the configuration SCR.
Bridges perform a variety of functions:
•
•
•
Conversion between configuration bus and data bus.
Width conversion between peripheral bus width and SCR bus width.
Frequency conversion between peripheral bus frequency and SCR bus frequency.

4.3 Configuration Switch Fabric
A detailed figure will be added here for a future release. All masters can talk to all slaves on the configuration switch
fabric.
4.4 Bus Priorities
The priority level of all master peripheral traffic is defined at the TeraNet boundary. User programmable priority
registers will be present to allow software configuration of the data traffic through the TeraNet. Note that a lower
number means higher priority - PRI = 000b = urgent, PRI = 111b = low.
All other masters provide their priority directly and do not need a default priority setting. Examples include the
CorePacs, whose priorities are set through software in the UMC control registers. All the Packet DMA based
peripherals also have internal registers to define the priority level of their initiated transactions.
The Packet DMA secondary port is one master port that does not have priority allocation register inside the IP. The
priority level for transaction from this master port is described by PKTDMA_PRI_ALLOC register in Figure 4-1 and
Table 4-3.

5.1 Memory Architecture
The C66x CorePac of the TMS320C6671 device contains a 512KB level-2 memory (L2), a 32KB level-1 program
memory (L1P), and a 32KB level-1 data memory (L1D). The device also contain a 4096KB multicore shared memory
(MSM). All memory on the C6671 has a unique location in the memory map (see Table 2-2 ‘‘Memory Map
Summary for TMS320C6671’’ on page 19.
The L1P and L1D cache can be reconfigured via software through the L1PMODE field of the L1P Configuration
Register (L1PCFG) and the L1DMODE field of the L1D Configuration Register (L1DCFG) of the C66x CorePac.
L1D is a two-way set-associative cache, while L1P is a direct-mapped cache.
The on-chip bootloader changes the reset configuration for L1P and L1D. For more information, see the Bootloader
for the C66x DSP User Guide (literature number SPRUGY5).
For more information on the operation L1 and L2 caches, see the C66x DSP Cache User Guide (literature number
SPRUGY8).

L2 memory can be configured as all SRAM, all 4-way set-associative cache, or a mix of the two. The amount of L2
memory that is configured as cache is controlled through the L2MODE field of the L2 Configuration Register
(L2CFG) of the C66x CorePac. Figure 5-4 shows the available SRAM/cache configurations for L2. By default, L2 is
configured as all SRAM after device reset.

Global addresses are accessible to all masters in the system. In addition, local memory can be accessed directly by
the associated processor through aliased addresses, where the eight MSBs are masked to zero. The aliasing is handled
within the C66x CorePac and allows for common code to be run unmodified on multiple cores. For example, address
location 0x10800000 is the global base address for C66x CorePac Core 0's L2 memory. C66x CorePac Core 0 can
access this location by either using 0x10800000 or 0x00800000. Any other master on the device must use 0x10800000
only. Conversely, 0x00800000 can by used by any of the cores as their own L2 base addresses.
For C66x CorePac Core 0, as mentioned, this is equivalent to 0x10800000. Local addresses should be used only for
shared code or data, allowing a single image to be included in memory. Any code/data targeted to a specific core, or
a memory region allocated during run-time by a particular core should always use the global address only.
5.1.4 MSMC SRAM
The MSMC SRAM configuration for the C6671 device is as follows:
•
•
•
•
Memory size is 4096KB
The MSMC SRAM can be configured as shared L2 and/or shared L3 memory
Allows extension of external addresses from 2GB to up to 8GB
Has built in memory protection features
88
Copyright 2011 Texas Instruments Incorporated
TMS320C6671
Fixed and Floating-Point Digital Signal Processor
SPRS756A—July 2011
www.ti.com
The MSM SRAM is always configured as all SRAM. When configured as a shared L2, its contents can be cached in
L1P and L1D. When configured in shared L3 mode, it’s contents can be cached in L2 also. For more details on
external memory address extension and memory protection features, see the Multicore Shared Memory Controller
(MSMC) for KeyStone Devices User Guide (literature number SPRUGW7).
5.1.5 L3 Memory
The L3 ROM on the device is 128KB. The ROM contains software used to boot the device. There is no requirement
to block accesses from this portion to the ROM.
5.2 Memory Protection
Memory protection allows an operating system to define who or what is authorized to access L1D, L1P, and L2
memory. To accomplish this, the L1D, L1P, and L2 memories are divided into pages. There are 16 pages of L1P (2KB
each), 16 pages of L1D (2KB each), and 32 pages of L2 (16KB each). The L1D, L1P, and L2 memory controllers in
the C66x CorePac are equipped with a set of registers that specify the permissions for each memory page.
Each page may be assigned with fully orthogonal user and supervisor read, write, and execute permissions. In
addition, a page may be marked as either (or both) locally accessible or globally accessible. A local access is a direct
DSP access to L1D, L1P, and L2, while a global access is initiated by a DMA (either IDMA or the EDMA3) or by
other system masters. Note that EDMA or IDMA transfers programmed by the DSP count as global accesses. On a
secure device, pages can be restricted to secure access only (default) or opened up for public, non-secure access.
The DSP and each of the system masters on the device are all assigned a privilege ID. It is possible to specify whether
memory pages are locally or globally accessible.
The AIDx and LOCAL bits of the memory protection page attribute registers specify the memory page protection
scheme, see Table 5-1.

End of Table 5-1
Faults are handled by software in an interrupt (or an exception, programmable within the C66x CorePac interrupt
controller) service routine. A DSP or DMA access to a page without the proper permissions will:
•
•
•
Block the access — reads return zero, writes are ignored
Capture the initiator in a status register — ID, address, and access type are stored
Signal event to DSP interrupt controller
The software is responsible for taking corrective action to respond to the event and resetting the error status in the
memory controller. For more information on memory protection for L1D, L1P, and L2, see the C66x CorePac User
Guide (literature number SPRUGW0).

5.3 Bandwidth Management
When multiple requestors contend for a single C66x CorePac resource, the conflict is resolved by granting access to
the highest priority requestor. The following four resources are managed by the Bandwidth Management control
hardware:
•
•
•
•
Level 1 Program (L1P) SRAM/Cache
Level 1 Data (L1D) SRAM/Cache
Level 2 (L2) SRAM/Cache
Memory-mapped registers configuration bus
The priority level for operations initiated within the C66x CorePac are declared through registers in the C66x
CorePac. These operations are:
•
•
•
DSP-initiated transfers
User-programmed cache coherency operations
IDMA-initiated transfers
The priority level for operations initiated outside the C66x CorePac by system peripherals is declared through the
Priority Allocation Register (PRI_ALLOC) System peripherals with no fields in PRI_ALLOC have their own
registers to program their priorities, see section 4.4 ‘‘Bus Priorities’’ on page 84 for more details.
More information on the bandwidth management features of the C66x CorePac can be found in the C66x CorePac
User Guide (literature number SPRUGW0.)
5.4 Power-Down Control
The C66x CorePac supports the ability to power-down various parts of the C66x CorePac. The power-down
controller (PDC) of the C66x CorePac can be used to power down L1P, the cache control hardware, the DSP, and
the entire C66x CorePac. These power-down features can be used to design systems for lower overall system power
requirements.
Note—The C6671 does not support power-down modes for the L2 memory at this time.
More information on the power-down features of the C66x CorePac can be found in the TMS320C66x CorePac
Reference Guide (literature number SPRUGW0).
5.5 C66x CorePac Revision
The version and revision of the C66x CorePac can be read from the CorePac Revision ID Register (MM_REVID)
located at address 0181 2000h. The MM_REVID register is shown in Figure 5-5 and described in Table 5-2. The
C66x CorePac revision is dependant on the silicon revision being used.

7 Peripheral Information and Electrical Specifications
This chapter covers the various peripherals on the TMS320C6671 DSP. Peripheral-specific information, timing
diagrams, electrical specifications, and register memory maps are described in this chapter.
7.1 Parameter Information
This section describes the conditions used to capture the electrical data seen in this chapter.
The data manual provides timing at the device pin. For output analysis, the transmission line and associated
parasitics (vias, multiple nodes, etc.) must also be taken into account. The transmission line delay varies depending
on the trace length. An approximate range for output delays can vary from 176 ps to 2 ns depending on the end
product design. For recommended transmission line lengths, see the appropriate application notes, user guides, and
design guides. A transmission line delay of 2 ns was used for all output measurements, except the DDR3, which was
evaluated using a 528-ps delay.
Figure 7-1 represents all device outputs, except differential or I2C.

Vref = VIH MIN (or VOH MIN)
7.1.2 Timing Parameters and Board Routing Analysis
The timing parameter values specified in this data sheet do not include delays by board routings. As a good board
design practice, such delays must always be taken into account. Timing values may be adjusted by
increasing/decreasing such delays. TI recommends using the available I/O buffer information specification (IBIS)
models to analyze the timing characteristics correctly. To properly use IBIS models to attain accurate timing analysis
for a given system, see the Using IBIS Models for Timing Analysis application report (literature number TBD). If
needed, external logic hardware such as buffers may be used to compensate any timing differences.
For inputs, timing is most impacted by the round-trip propagation delay from the DSP to the external device and
from the external device to the DSP. This round-trip delay tends to negatively impact the input setup time margin,
but also tends to improve the input hold time margins (see Table 7-1 and Figure 7-4).

3. DVDD18, AVDD1, AVDD2
4. DVDD15, VDDR1-4
The second sequence provides compatibility with other TI processors with the IO voltage starting before the core
voltages as shown below.

The clock input buffers for CORECLK, DDRCLK, PASSCLK, SRIOSGMIICLK, PCIECLK and MCMCLK
use CVDD as a supply voltage. These clock inputs are not failsafe and must be held in a high-impedance state until
CVDD is at a valid voltage level. Driving these clock inputs high before CVDD is valid could cause damage to the
device. Once CVDD is valid it is acceptable that the P and N legs of these CLKs may be held in a static state (either
high and low or low and high) until a valid clock frequency is needed at that input. To avoid internal oscillation the
clock inputs should be removed from the high impedance state shortly after CVDD is present.
If a clock input is not used it must be held in a static state. To accomplish this the N leg should be pulled to ground
through a 1K ohm resistor. The P leg should be tied to CVDD to ensure it won't have any voltage present until
CVDD is active. Connections to the IO cells powered by DVDD18 and DVDD15 are not failsafe and should not be
driven high before these voltages are active. Driving these IO cells high before DVDD18 or DVDD15 are valid could
cause damage to the device.
The device initialization is broken into two phases. The first phase consists of the time period from the activation of
the first power supply until the point in which all supplies are active and at a valid voltage level. Either of the
sequencing scenarios described above can be implemented during this phase. The figures below show both the
core-before-IO voltage sequence and the IO-before-core voltage sequence. POR must be held low for the entire
power stabilization phase.
This is followed by the device initialization phase. The rising edge of POR followed by the rising edge of RESETFULL
will trigger the end of the initialization phase but both must be inactive for the initialization to complete. POR must
always go inactive before RESETFULL goes inactive as described below. The following section mentions SYSCLK1
in several places. SYSCLK1 here refers to the clock input that has been selected as the source for the Main PLL. See
Figure 7-11 for more details.
7.3.1.1 Core-Before-IO Power Sequencing
Figure 7-5 shows the power sequencing and reset control of TMS320C6671 for device initialization. POR may be
removed after the power has been stable for the required 100 μsec. RESETFULL must be held low for a period after
the rising edge of POR but may be held low for longer periods if necessary. The configuration bits shared with the
GPIO pins will be latched on the rising edge of RESETFULL and must meet the setup and hold times specified.
SYSCLK1 must always be active before POR can be removed. Core-before-IO power sequencing is defined in
Table 7-3.
Note—TI recommends a maximum of 100 ms between one power rail being valid, and the next power rail
in the sequence starting to ramp

• Once CVDD is valid, the clock drivers should be enabled. Although the clock inputs are not necessary at this time, they should either be
driven with a valid clock or be held in a static state with one leg high and one leg low.

End of Table 7-4
7.3.1.3 Prolonged Resets
Holding the device in POR, RESETFULL, or RESET for long periods of time will affect the long term reliability of
the part. The device should not be held in a reset for times exceeding one hour and should not be held in reset for
more the 5% of the time during which power is applied. Exceeding these limits will cause a gradual reduction in the
reliability of the part. This can be avoided by allowing the DSP to boot and then configuring it to enter a hibernation
state soon after power is applied. This will satisfy the reset requirement while limiting the power consumption of the
device.
7.3.1.4 Clocking during power sequencing
Some of the clock inputs are required to be present for the device to initialize correctly, but behavior of many of the
clocks is contingent on the state of the boot configuration pins. Table 7-5 describes the clock sequencing and the
conditions that affect the clock operation. Note that all clock drivers should be in a high-impedance state until
CVDD is at a valid level and that all clock inputs either be active or in a static state with one leg pulled low and the
other connected to CVDD.

End of Table 7-5
7.3.2 Power-Down Sequence
The power down sequence is the exact reverse of the power-up sequence described above. The goal is to prevent a
large amount of static current and to prevent overstress of the device. A power-good circuit that monitors all the
supplies for the device should be used in all designs. If a catastrophic power supply failure occurs on any voltage rail,
POR should transition to low to prevent over-current conditions that could possibly impact device reliability.
A system power monitoring solution is needed to shut down power to the board if a power supply fails. Long-term
exposure to an environment in which one of the power supply voltages is no longer present will affect the reliability
of the device. Holding the device in reset is not an acceptable solution because prolonged periods of time with an
active reset can also affect long term reliability.
7.3.3 Power Supply Decoupling and Bulk Capacitors
In order to properly decouple the supply planes on the PCB from system noise, decoupling and bulk capacitors are
required. Bulk capacitors are used to minimize the effects of low frequency current transients and decoupling or
bypass capacitors are used to minimize higher frequency noise. For recommendations on selection of Power Supply
Decoupling and Bulk capacitors see the Hardware Design Guide for KeyStone Devices (literature number SPRABI2).
7.3.4 SmartReflex
Increasing the device complexity increases its power consumption and with the smaller transistor structures
responsible for higher achievable clock rates and increased performance, comes an inevitable penalty, increasing the
leakage currents. Leakage currents are present in any active circuit, independently of clock rates and usage scenarios.
This static power consumption is mainly determined by transistor type and process technology. Higher clock rates
also increase dynamic power, the power used when transistors switch. The dynamic power depends mainly on a
specific usage scenario, clock rates, and I/O activity.
Texas Instruments' SmartReflex technology is used to decrease both static and dynamic power consumption while
maintaining the device performance. SmartReflex in the TMS320C6671 device is a feature that allows the core
voltage to be optimized based on the process corner of the device. This requires a voltage regulator for each
TMS320C6671 device.
Copyright 2011 Texas Instruments Incorporated

TMS320C6671
Fixed and Floating-Point Digital Signal Processor
SPRS756A—July 2011
www.ti.com
To guarantee maximizing performance and minimizing power consumption of the device, SmartReflex is required
to be implemented whenever the TMS320C6671 device is used. The voltage selection is done using 4 VCNTL pins
which are used to select the output voltage of the core voltage regulator.
For information on implementation of SmartReflex see the Power Management for KeyStone Devices application
report and the Hardware Design Guide for KeyStone Devices (literature number SPRABI2).

7.4 Power Sleep Controller (PSC)
The Power Sleep Controller (PSC) controls overall device power by turning off unused power domains and gating
off clocks to individual peripherals and modules. The PSC provides the user with an interface to control several
important power and clock operations.
For information on the Power Sleep Controller, see the Power Sleep Controller (PSC) for KeyStone Devices User
Guide (literature number SPRUGV4).
7.4.1 Power Domains
The device has several power domains that can be turned on for operation or off to minimize power dissipation. The
global power/sleep controller (GPSC) is used to control the power gating of various power domains.

7.4.2 Clock Domains
Cock gating to each logic block is managed by the local power/sleep controllers (LPSCs) of each module. For
modules with a dedicated clock or multiple clocks, the LPSC communicates with the PLL controller to enable and
disable that module's clock(s) at the source. For modules that share a clock with other modules, the LPSC controls
the clock gating.

7.5 Reset Controller
The reset controller detects the different type of resets supported on the TMS320C6671 device and manages the
distribution of those resets throughout the device.
The device has several types of resets:
•
•
•
•
Power-on reset
Hard reset
Soft reset
CPU local reset
Table 7-10 explains further the types of reset, the reset initiator, and the effects of each reset on the device. For more
information on the effects of each reset on the PLL controllers and their clocks, see Section ‘‘Reset Electrical Data /
Timing’’ on page 115
Table 7-10

Resets everything except for test/emu logic and Reset Isolation
modules. Emulator and Reset Isolation modules stay alive during this
reset. This reset is also different from POR in that the PLLCTL assumes
power and clocks are stable when Device Reset is asserted. Boot
configurations are not latched. ROM boot process is initiated.

7.5.1 Power-on Reset
Power-on reset is used to reset the entire device, including the test and emulation logic.
Power-on reset is initiated by the following
1. POR pin
2. RESETFULL pin
During power-up, the POR pin must be asserted (driven low) until the power supplies have reached their normal
operating conditions. A RESETFULL pin is also provided to allow the on-board host to reset the entire device
including the reset isolated logic. The assumption is that, device is already powered up and hence unlike POR,
RESETFULL pin will be driven by the on-board host control other than the power good circuitry. For power-on
reset, the Main PLL controller comes up in bypass mode and the PLL is not enabled. Other resets do not affect the
state of the PLL or the dividers in the PLL controller.

TMS320C6671
Fixed and Floating-Point Digital Signal Processor
SPRS756A—July 2011
www.ti.com
The following sequence must be followed during a power-on reset:
1. Wait for all power supplies to reach normal operating conditions while keeping the POR pin asserted (driven
low). While POR is asserted, all pins except RESETSTAT will be set to high-impedance. After the POR pin is
de-asserted (driven high), all Z group pins, low group pins, and high group pins are set to their reset state and
will remain at their reset state until otherwise configured by their respective peripheral. All peripherals that are
power managed, are disabled after a Power-on Reset and must be enabled through the Device State Control
registers (for more details, see Section Table 3-2 ‘‘Device State Control Registers’’ on page 65).
2. Clocks are reset, and they are propagated throughout the chip to reset any logic that was using reset
synchronously. All logic is now reset and RESETSTAT will be driven low indicating that the device is in reset.
3. POR must be held active until all supplies on the board are stable then for at least an additional time for the
Chip level PLLs to lock.
4. The POR pin can now be de-asserted. Reset sampled pin values are latched at this point. The Chip level PLLs
is taken out of reset and begins its locking sequence, and all power-on device initialization also begins.
5. After device initialization is complete, the RESETSTAT pin is de-asserted (driven high). By this time, DDR3
PLL has already completed its locking sequence and is outputting a valid clock. The system clocks of both PLL
controllers are allowed to finish their current cycles and then paused for 10 cycles of their respective system
reference clocks. After the pause, the system clocks are restarted at their default divide by settings.
6. The device is now out of reset and device execution begins as dictated by the selected boot mode.
Note—To most of the device, reset is de-asserted only when the POR and RESET pins are both de-asserted
(driven high). Therefore, in the sequence described above, if the RESET pin is held low past the low period
of the POR pin, most of the device will remain in reset. The RESET pin should not be tied together with the
POR pin.
7.5.2 Hard Reset
A Hard reset will reset everything on the device except the PLLs, test, emulation logic, and reset isolation modules.
POR should also remain de-asserted during this time.
Hard reset is initiated by the following
•
•
•
•
RESET pin
RSCTRL register in PLLCTL
Watchdog timer
Emulation
All the above initiators by default are configured to act as Hard reset. Except Emulation all the other 3 initiators can
be configured as Soft resets in the RSCFG register in PLLCTL.
The following sequence must be followed during a Hard reset:
1. The RESET pin is pulled active low for a minimum of 24 CLKIN1 cycles. During this time the RESET signal is
able to propagate to all modules (except those specifically mentioned above). All I/O are Hi-Z for modules
affected by RESET, to prevent off-chip contention during the warm reset.
2. Once all logic is reset, RESETSTAT is driven active to denote that the device is in reset.
3. The RESET pin can now be released. A minimal device initialization begins to occur. Note that configuration
pins are not re-latched and clocking is unaffected within the device.
4. After device initialization is complete, the RESETSTAT pin is de-asserted (driven high).
Note—The POR pin should be held inactive (high) throughout the warm reset sequence. Otherwise, if POR
is activated (brought low), the minimum POR pulse width must be met. The RESET pin should not be tied
together with the POR pin.

7.5.3 Soft Reset
A soft reset will behave like a hard reset except that the PCIe MMRs and DDR3 EMIF MMRs contents are retained.
POR should also remain de-asserted during this time.
Soft reset is initiated by the following
•
•
•
•
RESET pin
RSCTRL register in PLLCTL
Watchdog Timer
Emulation
All the above initiators by default are configured to act as Hard reset. Except Emulation, all the other 3 initiators can
be configured as Soft resets in the RSCFG register in PLLCTL.
In the case of a soft reset, the clock logic or the power control logic of the peripherals are not affected, and, therefore,
the enabled/disabled state of the peripherals is not affected. The following external memory contents are maintained
during a soft reset:
•
DDR3 MMRs: The DDR3 Memory Controller registers are not reset. In addition, the DDR3 SDRAM memory
content is retained if the user places the DDR3 SDRAM in self-refresh mode before invoking the soft reset.
•
PCIe MMRs: The contents of the memory connected to the EMIFA are retained. The EMIFA registers are not
reset.
During a soft reset, the following happens:
1. The RESETSTAT pin goes low to indicate an internal reset is being generated. The reset is allowed to propagate
through the system. Internal system clocks are not affected. PLLs also remain locked.
2. After device initialization is complete, the RESETSTAT pin is deasserted (driven high). In addition, the PLL
controllers pause their system clocks for about 8 cycles.
At this point:
›
›
›
The state of the peripherals before the soft reset is not changed.
The I/O pins are controlled as dictated by the DEVSTAT register.
The DDR3 MMRs and PCIe MMRs retain their previous values. Only the DDR3 Memory Controller
and PCIe state machines are reset by the soft reset.
›
The PLL controllers are operating in the mode prior to soft reset. System clocks are unaffected.
The boot sequence is started after the system clocks are restarted. Since the configuration pins are not latched with
a System Reset, the previous values, as shown in the DEVSTAT register, are used to select the boot mode.

Note—The Main PLL controller registers can be accessed by any master in the device.
Note—NOTE: PLLM[5:0] bits of the multiplier are controlled by the PLLM register inside the PLL controller
and PLLM[12:6] bits are controlled by the chip level MAINPLLCTL0 register. The complete 13-bit value is
latched when the GO operation is initiated in the PLL controller. Only PLLDIV2, PLLDIV5, and PLLDIV8
are programmable on the C6671 device. See the Phase Locked Loop (PLL) Controller for KeyStone Devices
User Guide in section 2.10 ‘‘Related Documentation from Texas Instruments’’ on page 63 for more details
on how to program the PLL controller.
The Main PLL is controlled by the standard PLL controller. The PLL controller manages the clock ratios, alignment,
and gating for the system clocks to the device. Figure 7-11 shows a block diagram of the main PLL controller. The
following paragraphs define the clocks and PLL controller parameters.
The inputs, multiply factor within the PLL, and post-division for each of the chip-level clocks from the PLL output.
The PLL controller also controls reset propagation through the chip, clock alignment, and test points. The PLL
controller monitors the PLL status and provides an output signal indicating when the PLL is locked.
Main PLL power is supplied externally via the Main PLL power-supply pin (AVDDA1). An external EMI filter
circuit must be added to all PLL supplies. See the Hardware Design Guide for KeyStone Devices (literature number
SPRABI2) for detailed recommendations. For the best performance, TI recommends that all the PLL external
components be on a single side of the board without jumpers, switches, or components other than those shown. For
reduced PLL jitter, maximize the spacing between switching signal traces and the PLL external components (C1, C2,
and the EMI Filter).
The minimum SYSCLK rise and fall times should also be observed. For the input clock timing requirements, see
Section 7.6.4 ‘‘Main PLL Controller/SRIO/HyperLink/PCIe Clock Input Electrical Data/Timing’’.
CAUTION—The PLL controller module as described in the see the Phase Locked Loop (PLL) Controller for
KeyStone Devices User Guide (literature number SPRUGV2) includes a superset of features, some of which
are not supported on the TMS320C6671 device. The following sections describe the registers that are
supported; it should be assumed that any registers not included in these sections is not supported by the
device. Furthermore, only the bits within the registers described here are supported. Avoid writing to any
reserved memory location or changing the value of reserved bits.
7.6.1 Main PLL Controller Device-Specific Information
7.6.1.1 Internal Clocks and Maximum Operating Frequencies
The Main PLL, used to drive the CorePacs, the switch fabric, and a majority of the peripheral clocks (all but the
DDR3 and the network coprocessor (PASS)) requires a PLL controller to manage the various clock divisions, gating,
and synchronization. The Main PLL’s PLL controller has several SYSCLK outputs that are listed below, along with
the clock description. Each SYSCLK has a corresponding divider that divides down the output clock of the PLL. Note
that dividers are not programmable unless explicitly mentioned in the description below.
•
•
SYSCLK1: Full-rate clock for the CorePac.
SYSCLK2: 1/x-rate clock for CorePac (emulation) and the ADTF module. Default rate for this will be 1/3. This
is programmable from /1 to /32, where this clock does not violate the max of 350 MHz. The SYSCLK2 can be
turned off by software.
•
•
SYSCLK3: 1/2-rate clock used to clock the MSMC, HyperLink, CPU/2 SCR, DDR EMIF and CPU/2 EDMA.
SYSCLK4: 1/3-rate clock for the switch fabrics and fast peripherals. The Debug_SS and ETBs will use this as
well.
118

TMS320C6671
Fixed and Floating-Point Digital Signal Processor
SPRS756A—July 2011
www.ti.com
•
SYSCLK5: 1/y-rate clock for system trace module only. Default rate for this will be 1/5. It is configurable and
the max configurable clock is 210 MHz and min configuration clock is 32 MHz. The SYSCLK5 can be turned
off by software.
•
SYSCLK6: 1/64-rate clock. 1/64 rate clock (emif_ptv) used to clock the PVT compensated buffers for DDR3
EMIF.
•
•
SYSCLK7: 1/6-rate clock for slow peripherals and sources the SYSCLKOUT output pin.
SYSCLK8: 1/z-rate clock. This clock is used as slow_sysclck in the system. Default for this will be 1/64. This is
programmable from /24 to /80.
•
•
•
SYSCLK9: 1/12-rate clock for SmartReflex.
SYSCLK10: 1/3-rate clock for SRIO only.
SYSCLK11: 1/6-rate clock for PSC only.
Only SYSCLK2, SYSCLK5 and SYSCLK8 are programmable on theTMS320C6671 device.
Note—In case any of the other programmable SYSCLKs are set slower than 1/64 rate, then SYSCLK8
(SLOW_SYSCLK) needs to be programmed to either match, or be slower than, the slowest SYSCLK in the
system.
7.6.1.2 Main PLL Controller Operating Modes
The Main PLL controller has two modes of operation: bypass mode and PLL mode. The mode of operation is
determined by BYPASS bit of the PLL Secondary control register (SECCTL). In PLL mode, SYSCLK1 is generated
from the PLL output using the divider PLLD and the PLL multiplier PLLM. In bypass mode, PLL output is fed
directly to SYSCLK1.
All hosts must hold off accesses to the DSP while the frequency of its internal clocks is changing. A mechanism must
be in place such that the DSP notifies the host when the PLL configuration has completed.
7.6.1.3 Main PLL Stabilization, Lock, and Reset Times
The PLL stabilization time is the amount of time that must be allotted for the internal PLL regulators to become
stable after device powerup. The PLL should not be operated until this stabilization time has expired.
The PLL reset time is the amount of wait time needed when resetting the PLL (writing PLLRST = 1), in order for the
PLL to properly reset, before bringing the PLL out of reset (writing PLLRST = 0). For the Main PLL reset time value,
see Table 7-14.
The PLL lock time is the amount of time needed from when the PLL is taken out of reset (PLLRST = 1 with
PLLEN = 0) to when to when the PLL controller can be switched to PLL mode (PLLEN = 1). The Main PLL lock time
is given in Table 7-14.

7.6.2.4 PLLDIV Divider Ratio Change Status Register (DCHANGE)
Whenever a different ratio is written to the PLLDIVn registers, the PLLCTL flags the change in the DCHANGE
status register. During the GO operation, the PLL controller will change only the divide ratio of the SYSCLKs with
the bit set in DCHANGE. Note that the ALNCTL register determines if that clock also needs to be aligned to other
clocks. The PLLDIV divider ratio change status register is shown in Figure 7-15 and described in Table 7-19.

7.6.2.9 Reset Isolation Register (RSISO)
This register is used to select the module clocks that must maintain their clocking without pausing through non
power-on reset. Setting any of these bits effectively blocks reset to all PLLCTL registers in order to maintain current
values of PLL multiplier, divide ratios and other settings. The Reset Isolation Register (RSTCTRL) is shown in
Figure 7-20 and described in Table 7-24.

7.6.3 Main PLL Control Register
The Main PLL uses two chip-level registers (MAINPLLCTL0 and MAINPLLCTL1) along with the PLL controller
for its configuration. These MMRs exist inside the Bootcfg space. To write to these registers, software should go
through an un-locking sequence using KICK0/KICK1 registers. For valid configurable values into the
MAINPLLCTL0 and MAINPLLCTL1 registers see Section 2.5.3 ‘‘PLL Boot Configuration Settings’’ on page 31. See
section 3.3.4 ‘‘Kicker Mechanism (KICK0 and KICK1) Register’’ on page 70 for the address location of the registers
and locking and unlocking sequences for accessing the registers. The registers are reset on POR only.

End of Table 7-26
Note—PLLM[5:0] bits of the multiplier is controlled by the PLLM register inside the PLL controller
and PLLM[12:6] bits are controlled by the MAINPLLCTL0 chip-level register. The MAINPLLCTL0 register
PLLM[12:6] bits should be written just before writing to the PLLM register PLLM[5:0] bits in the controller
to have the complete 13 bit value latched when the GO operation is initiated in the PLL controller. See the
Phase Locked Loop (PLL) Controller for KeyStone Devices User Guide (literature number SPRUGV2) for the
recommended programming sequence. Output Divide ratio and Bypass enable/disable of the Main PLL is
controlled by the SECCTL register in the PLL Controller. See the 7.6.2.1 ‘‘PLL Secondary Control Register

7.7 DD3 PLL
The DDR3 PLL generates interface clocks for the DDR3 memory controller. When coming out of power-on reset,
DDR3 PLL is programmed to a valid frequency during the boot config before being enabled and used.
DDR3 PLL power is supplied externally via the Main PLL power-supply pin (AVDDA2). An external EMI filter
circuit must be added to all PLL supplies. See the Hardware Design Guide for KeyStone Devices (literature number
SPRABI2). For the best performance, TI recommends that all the PLL external components be on a single side of the
board without jumpers, switches, or components other than those shown. For reduced PLL jitter, maximize the
spacing between switching signal traces and the PLL external components (C1, C2, and the EMI Filter).

7.7.1 DDR3 PLL Control Register
The DDR3 PLL, which is used to drive the DDR PHY for the EMIF, does not use a PLL controller. DDR3 PLL can
be controlled using the DDR3PLLCTL0 and DDR3PLLCTL1 registers located in the Bootcfg module. These MMRs
exist inside the Bootcfg space. To write to these registers, software should go through an un-locking sequence using
KICK0/KICK1 registers. For suggested configurable values see section 3.3.4 ‘‘Kicker Mechanism (KICK0 and
KICK1) Register’’ on page 70 for the address location of the registers and locking and unlocking sequences for
accessing the registers. This register is reset on POR only

PLL are affected as described in Section 7.5 ‘‘Reset Controller’’ on page 112. DDR3 PLL is unlocked only during the
power-up sequence and is locked by the time the RESETSTAT pin goes high. It does not lose lock during any of the
other resets.

7.8 PASS PLL
The PASS PLL generates interface clocks for the Network Coprocessor. Using the PACLKSEL pin the user can select
the input source of PASS PLL as either the output of Main PLL mux or the PASSCLK clock reference sources. When
coming out of power-on reset, PASS PLL comes out in a bypass mode and needs to be programmed to a valid
frequency before being enabled and used.
PASS PLL power is supplied externally via the Main PLL power-supply pin (AVDDA3). An external EMI filter
circuit must be added to all PLL supplies. Please see the Hardware Design Guide for KeyStone Devices (literature
number SPRABI2). for detailed recommendations. For the best performance, TI recommends that all the PLL
external components be on a single side of the board without jumpers, switches, or components other than those
shown. For reduced PLL jitter, maximize the spacing between switching signal traces and the PLL external
components (C1, C2, and the EMI Filter).

7.9 Enhanced Direct Memory Access (EDMA3) Controller
The primary purpose of the EDMA3 is to service user-programmed data transfers between two memory-mapped
slave endpoints on the device. The EDMA3 services software-driven paging transfers (e.g., data movement between
external memory and internal memory), performs sorting or subframe extraction of various data structures, services
event driven peripherals, and offloads data transfers from the device CPU.
There are 3 EDMA Channel Controllers on the C6671 DSP, TPCC0, TPCC1, and TPCC2. TPCC0 is optimized to
be used for transfers to/from/within the MSMC and DDR-3 Subsytems. The others are to be used for the remaining
traffic.
Each EDMA3 Channel Controller includes the following features:
•
Fully orthogonal transfer description
–
3 transfer dimensions:
›
›
›
Array (multiple bytes)
Frame (multiple arrays)
Block (multiple frames)
–
–
Single event can trigger transfer of array, frame, or entire block
Independent indexes on source and destination
•
•
Flexible transfer definition:
–
–
Increment or FIFO transfer addressing modes
Linking mechanism allows for ping-pong buffering, circular buffering, and repetitive/continuous
transfers, all with no CPU intervention
–
Chaining allows multiple transfers to execute with one event
128 PaRAM entries for TPCC0, 512 each for TPCC1 and TPCC2
–
–
Used to define transfer context for channels
Each PaRAM entry can be used as a DMA entry, QDMA entry, or link entry
•
•
16 DMA channels for TPCC0, 64 each for TPCC1 and TPCC2
–
Manually triggered (CPU writes to channel controller register), external event triggered, and chain
triggered (completion of one transfer triggers another)
8 Quick DMA (QDMA) channels per EDMA 3 Channel Controller
–
–
Used for software-driven transfers
Triggered upon writing to a single PaRAM set entry
•
2 transfer controllers and 2 event queues with programmable system-level priority for TPCC0, 4 transfer
controllers and 4 event queues with programmable system-level priority per channel controller for TPCC1 and
TPCC2
•
•
Interrupt generation for transfer completion and error conditions
Debug visibility
–
–
Queue watermarking/threshold allows detection of maximum usage of event queues
Error and status recording to facilitate debug

In the context of this document, TPTCs associated with TPCC0 are referred to as TPCC0 TPTC0 and1. TPTCs
associated with TPCC1 and 2 are each referred to as TPCCx TPTC0 - 3, where x is 1 or 2. Each of the transfer
controllers has a direct connection to the switched central resource (SCR). Table 4-1 ‘‘CPU/2 Data SCR Connection
Matrix’’ on page 82 and Table 4-2 ‘‘DSP/3 Data SCR Connection Matrix’’ on page 82 lists the peripherals that can be
accessed by the transfer controllers.
7.9.1 EDMA3 Device-Specific Information
The EDMA supports two addressing modes: constant addressing and increment addressing mode. Constant
addressing mode is applicable to a very limited set of use cases; for most applications increment mode must be used.
On the C6671 DSP, the EDMA can use constant addressing mode only with the Enhanced Viterbi-Decoder
Coprocessor (VCP) and the Enhanced Turbo Decoder Coprocessor (TCP). Constant addressing mode is not
supported by any other peripheral or internal memory in the DSP. Note that increment mode is supported by all
peripherals, including VCP and TCP. For more information on these two addressing modes, see the Enhanced Direct
Memory Access 3 (EDMA3) for KeyStone Devices User Guide (literature number SPRUGS5).
For the range of memory addresses that include EDMA3 Channel Controller (TPCC) Control Registers and
EDMA3 Transfer Controller (TPTC) Control Register see Section Table 2-2‘‘Memory Map Summary for
TMS320C6671’’ on page 19. For memory offsets and other details on TPCC and TPTC Control Registers entries, see
the Enhanced Direct Memory Access 3 (EDMA3) for KeyStone Devices User Guide (literature number SPRUGS5) for
offset addresses on Parameter RAM (PaRAM) registers.

7.9.3 EDMA3 Transfer Controller Configuration
Each transfer controller on a device is designed differently based on considerations like performance requirements,
system topology (like main TeraNet bus width, external memory bus width), etc. The parameters that determine the
transfer controller configurations are:
•
FIFOSIZE: Determines the size in bytes for the Data FIFO that is the temporary buffer for the in-flight data.
The data FIFO is where the read return data read by the TC read controller from the source endpoint is stored
and subsequently written out to the destination endpoint by the TC write controller.
•
•
•
BUSWIDTH: The width of the read and write data buses in bytes, for the TC read and write controller,
respectively. This is typically equal to the bus width of the main TeraNet interface.
Default Burst Size (DBS): The DBS is the maximum number of bytes per read/write command issued by a
transfer controller.
DSTREGDEPTH: This determines the number of Destination FIFO register set. The number of Destination
FIFO register set for a transfer controller determines the maximum number of outstanding transfer requests.

7.9.4 EDMA3 Channel Synchronization Events
The EDMA3 supports up to 16 DMA channels for TPCC0, 64 each for TPCC1 and TPCC2 that can be used to
service system peripherals and to move data between system memories. DMA channels can be triggered by
synchronization events generated by system peripherals. The following tables lists the source of the synchronization
event associated with each of the EDMA TPCC DMA channels. On the C6671, the association of each
synchronization event and DMA channel is fixed and cannot be reprogrammed.
For more detailed information on the EDMA3 module and how EDMA3 events are enabled, captured, processed,
prioritized, linked, chained, and cleared, etc., see the Enhanced Direct Memory Access 3 (EDMA3) for KeyStone
Devices User Guide (literature number SPRUGS5).

7.10 Interrupts
7.10.1 Interrupt Sources and Interrupt Controller
The CPU interrupts on the C6671 device are configured through the C66x CorePac Interrupt Controller. The
interrupt controller allows for up to 128 system events to be programmed to any of the twelve CPU interrupt inputs
(CPUINT4 - CPUINT15), the CPU exception input (EXCEP), or the advanced emulation logic. The 128 system
events consist of both internally-generated events (within the CorePac) and chip-level events.
Additional system events are routed to each of the C66x CorePacs to provide chip-level events that are not required
as CPU interrupts/exceptions to be routed to the interrupt controller as emulation events. Additionally, error-class
events or infrequently used events are also routed through the system event router to offload the C66x CorePac
interrupt selector. This is accomplished through INTC blocks, INTC[2:0], with one controller per C66x CorePac.
This is clocked using CPU/6.
The event controllers consist of simple combination logic to provide additional events to the C66x CorePac, plus the
TPCC and INTC0 provide 17 additional events as well as 8 broadcast events to the C66x CorePac, INTC2 provides
26 and 24 additional events to TPCC1 and TPCC2 respectively, and INTC3 provides 8 and 32 additional events to
TPCC0 and HyperLink respectively.
There are a large amount of events on the chip level. The chip level INTC provides a flexible way to combine and
remap those events. Multiple events can be combined to a single event through chip level INTC. However, an event
can only be mapped to a single event output from the chip level INTC. The chip level INTC also allows the software
to trigger system event through memory writes. For more details on the INTC features, please refer to the Interrupt
Controller (INTC) for KeyStone Devices User Guide (literature number SPRUGW4).
Note—Modules such as CP_MPU, CP_Tracer, and BOOT_CFG have level interrupts and EOI handshaking
interface. The EOI value is 0 for CP_MPU, CP_Tracer, and BOOT_CFG.

7.10.4 NMI and LRESET
Non-maskable interrupts (NMI) can be generated by chip-level registers and the LRESET can be generated by
software writing into LPSC registers. LRESET and NMI can also be asserted by device pins or watchdog timers. One
NMI pin and one LRESET pin are shared by all CorePacs on the device. The CORESEL[3:0] pins can be configured
to select between the CorePacs available as shown in Table 7-47.

7.11 Memory Protection Unit (MPU)
The C6671 supports four MPUs:
•
One MPU is used to protect main CORE/3 CFG SCR (CFG space of all slave devices on the SCR is protected
by the MPU).
•
•
Two MPUs are used for QM_SS (one for DATA PORT port and another is for CFG PORT port).
One MPU is used for Semaphore.
This section contains MPU register map and details of device-specific MPU registers only. For MPU features and
details of generic MPU registers, see the Memory Protection Unit (MPU) for KeyStone Devices User Guide (literature
number SPRUGW5).
The following tables show the configuration of each MPU and the memory regions protected by each MPU.

Table 7-51 shows the privilege ID of each CORE and every mastering peripheral. Table 7-51 also shows the privilege
level (supervisor vs. user), security level (secure vs. non-secure), and access type (instruction read vs. data/DMA read

Table 7-52 shows the master ID of each CORE and every mastering peripheral. Master IDs are used to determine
allowed connections between masters and slaves. Unlike privilege IDs, which can be shared across different masters,
master IDs are unique to each master.

1 Some of the CPPI-based peripherals require multiple master IDs. QMS_CDMA is assigned with 88,89,90,91, but only 88-89 are actually used. For PA_CPPI port, 56,57,58,59 are
assigned while only 1 (56) is actually used. There are two master ID values are assigned for the QM_second master port, one master ID for external linking RAM and the
other one for the PDSP/MCDM accesses.
2 The master ID for MSMC is for the transactions initiated by MSMC internally and sent to the DDR.
3 All CP_traces are set to the same master ID and bit 7 of the master ID needs to be 1.

7.11.2.1 Programmable Range n Start Address Register (PROGn_MPSAR)
The programmable address start register holds the start address for the range. This register is writeable by a
supervisor entity only. If NS = 0 (non-secure mode) in the associated MPPA register, then the register is also
writeable only by a secure entity.
The start address must be aligned on a page boundary. The size of the page is 1K byte. The size of the page determines
the width of the address field in MPSAR and MPEAR.

7.11.2.2 Programmable Range n End Address Register (PROGn_MPEAR)
The programmable address end register holds the end address for the range. This register is writeable by a supervisor
entity only. If NS = 0 (non-secure mode) in the associated MPPA register then the register is also only writeable by
a secure entity.
The end address must be aligned on a page boundary. The size of the page depends on the MPU number. The page
size for MPU1 is 1K byte and for MPU2 it is 64K bytes. The size of the page determines the width of the address field

7.12 DDR3 Memory Controller
The 64-bit DDR3 Memory Controller bus of the TMS320C6671 is used to interface to JEDEC standard-compliant
DDR3 SDRAM devices. The DDR3 external bus interfaces only to DDR3 SDRAM devices; it does not share the bus
with any other types of peripherals.
7.12.1 DDR3 Memory Controller Device-Specific Information
The TMS320C6671 includes one 64-bit wide 1.5-V DDR3 SDRAM EMIF interface. The DDR3 interface can operate
at 800 Mega Transfers per Second (MTS), 1033 MTS, 1333 MTS, and 1600 MTS.
Due to the complicated nature of the interface, a limited number of topologies will be supported to provide a 16-bit,
32-bit, or 64-bit interface.
The DDR3 electrical requirements are fully specified in the DDR Jedec Specification JESD79-3C. Standard DDR3
SDRAMs are available in 8- and 16-bit versions, allowing for the following bank topologies to be supported by the
interface:
•
•
•
•
•
•
•
•
•
•
72-bit: Five 16-bit SDRAMs (including 8 bits of ECC)
72-bit: Nine 8-bit SDRAMs (including 8 bits of ECC)
36-bit: Three 16-bit SDRAMs (including 4 bits of ECC)
36-bit: Five 8-bit SDRAMs (including 4 bits of ECC)
64-bit: Four 16-bit SDRAMs
64-bit: Eight 8-bit SDRAMs
32-bit: Two 16-bit SDRAMs
32-bit: Four 8-bit SDRAMs
16-bit: One 16-bit SDRAM
16-bit: Two 8-bit SDRAM
The approach to specifying interface timing for the DDR3 memory bus is different than on other interfaces such as
I2C or SPI. For these other interfaces, the device timing was specified in terms of data manual specifications and I/O
buffer information specification (IBIS) models. For the DDR3 memory bus, the approach is to specify compatible
DDR3 devices and provide the printed circuit board (PCB) solution and guidelines directly to the user.
A race condition may exist when certain masters write data to the DDR3 memory controller. For example, if
master A passes a software message via a buffer in external memory and does not wait for an indication that the write
completes, before signaling to master B that the message is ready, when master B attempts to read the software
message, then the master B read may bypass the master A write and, thus, master B may read stale data and,
therefore, receive an incorrect message.
Some master peripherals (e.g., EDMA3 transfer controllers with TCCMOD=0) will always wait for the write to
complete before signaling an interrupt to the system, thus avoiding this race condition. For masters that do not have
a hardware specification of write-read ordering, it may be necessary to specify data ordering via software.
If master A does not wait for indication that a write is complete, it must perform the following workaround:
1. Perform the required write to DDR3 memory space.
2. Perform a dummy write to the DDR3 memory controller module ID and revision register.
3. Perform a dummy read to the DDR3 memory controller module ID and revision register.
4. Indicate to master B that the data is ready to be read after completion of the read in step 3. The completion of
the read in step 3 ensures that the previous write was done.

7.12.2 DDR3 Memory Controller Electrical Data/Timing
The KeyStone DSP DDR3 Implementation Guidelines (literature number SPRABI1)specifies a complete DDR3
interface solution as well as a list of compatible DDR3 devices. The DDR3 electrical requirements are fully specified
in the DDR3 Jedec Specification JESD79-3C. TI has performed the simulation and system characterization to ensure
all DDR3 interface timings in this solution are met; therefore, no electrical data/timing information is supplied here
for this interface.
Note—TI supports only designs that follow the board design guidelines outlined in the application report.
7.13 I2C Peripheral
The inter-integrated circuit (I2C) module provides an interface between DSP and other devices compliant with
Philips Semiconductors Inter-IC bus (I2C bus) specification version 2.1 and connected by way of an I2C bus.
External components attached to this 2-wire serial bus can transmit/receive up to 8-bit data to/from the DSP
through the I2C module.
7.13.1 I2C Device-Specific Information
The TMS320C6671 device includes an I2C peripheral module.
Note—When using the I2C module, ensure there are external pullup resistors on the SDA and SCL pins.
The I2C modules on the C6671 may be used by the DSP to control local peripheral ICs (DACs, ADCs, etc.) or may
be used to communicate with other controllers in a system or to implement a user interface.
The I2C port is compatible with Philips I2C specification revision 2.1 (January 2000) and supports:
•
•
•
•
•
•
Fast mode up to 400 Kbps (no fail-safe I/O buffers)
Noise filter to remove noise 50 ns or less
7-bit and 10-bit device addressing modes
Multi-master (transmit/receive) and slave (transmit/receive) functionality
Events: DMA, interrupt, or polling
Slew-rate limited open-drain output buffers

1 The I2C pins SDA and SCL do not feature fail-safe I/O buffers. These pins could potentially draw current when the device is powered down
2 A Fast-mode I2C-bus™ device can be used in a Standard-mode I2C-bus™ system, but the requirement tsu(SDA-SCLH) ≥ 250 ns must then be met. This will automatically be the
case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch the LOW period of the SCL signal, it must output the next data bit to the
SDA line tr max + tsu(SDA-SCLH) = 1000 + 250 = 1250 ns (according to the Standard-mode I2C-Bus Specification) before the SCL line is released.
3 A device must internally provide a hold time of at least 300 ns for the SDA signal (referred to the VIHmin of the SCL signal) to bridge the undefined region of the falling edge
of SCL.
4 The maximum th(SDA-SCLL) has only to be met if the device does not stretch the low period [tw(SCLL)] of the SCL signal.
5 Cb = total capacitance of one bus line in pF. If mixed with HS-mode devices, faster fall-times are allowed.

7.16 UART Peripheral
The universal asynchronous receiver/transmitter (UART) module provides an interface between the DSP and
UART terminal interface or other UART-based peripheral. The UART is based on the industry standard TL16C550
asynchronous communications element, which in turn is a functional upgrade of the TL16C450. Functionally
similar to the TL16C450 on power up (single character or TL16C450 mode), the UART can be placed in an alternate
FIFO (TL16C550) mode. This relieves the DSP of excessive software overhead by buffering received and transmitted
characters. The receiver and transmitter FIFOs store up to 16 bytes including three additional bits of error status per
byte for the receiver FIFO.
The UART performs serial-to-parallel conversions on data received from a peripheral device and parallel-to-serial
conversion on data received from the DSP. The DSP can read the UART status at any time. The UART includes
control capability and a processor interrupt system that can be tailored to minimize software management of the
communications link. For more information on UART, see the Universal Asynchronous Receiver/Transmitter
(UART) for KeyStone Devices User Guide in 2.10 ‘‘Related Documentation from Texas Instruments’’ on page 63.

7.23 Management Data Input/Output (MDIO)
The management data input/output (MDIO) module implements the 802.3 serial management interface to
interrogate and controls up to 32 Ethernet PHY(s) connected to the device, using a shared two-wire bus. Application
software uses the MDIO module to configure the auto-negotiation parameters of each PHY attached to the GbE
switch subsystem, retrieve the negotiation results, and configure required parameters in the GbE switch subsystem
module for correct operation. The module is designed to allow almost transparent operation of the MDIO interface,
with very little maintenance from the core processor. For more information, see the Gigabit Ethernet (GbE) Switch
Subsystem for KeyStone Devices User Guide (literature number SPRUGV9)

7.24 Timers
The timers can be used to:
•
•
•
•
•
Time events
Count events
Generate pulses
Interrupt the CPU
Send synchronization events to the EDMA3 channel controller
7.24.1 Timers Device-Specific Information
The TMS320C6671 device has two 64-bit timers in total. Timer0 is dedicated to the CorePac as a watchdog timer
and can also be used as a general-purpose timer. Timer1 can also be configured as a general-purpose timer only,
programmed as a 64-bit timer or as two separate 32-bit timers.
When operating in 64-bit mode, the timer counts either VBUS clock cycles or input (TINPLx) pulses (rising edge)
and generates an output pulse/waveform (TOUTLx) plus an internal event (TINTLx) on a software-programmable
period.
When operating in 32-bit mode, the timer is split into two independent 32-bit timers. Each timer is made up of two
32-bit counters: a high counter and a low counter. The timer pins, TINPLx and TOUTLx are connected to the low
counter. The timer pins, TINPHx and TOUTHx are connected to the high counter.
When operating in Watchdog mode, the timer counts down to zero and generates an event. It is a requirement
that software writes to the timer before the count expires, after which the count begins again. If the count ever
reaches 0, the timer event output is asserted. Reset initiated by a watch dog timer can be set by programming ‘‘Reset
Type Status Register (RSTYPE)’’ on page 124 and the type of reset initiated can set by programming ‘‘Reset
Configuration Register (RSTCFG)’’ on page 125. For more information, see the 64-bit Timer (Timer 64) for KeyStone
Devices User Guide (literature number SPRUGV5).

7.25 Serial RapidIO (SRIO) Port
The SRIO port on the TMS320C6671 device is a high-performance, low pin-count interconnect aimed for
embedded markets. The use of the RapidIO interconnect in a baseband board design can create a homogeneous
interconnect environment, providing even more connectivity and control among the components. RapidIO is based
on the memory and device addressing concepts of processor buses where the transaction processing is managed
completely by hardware. This enables the RapidIO interconnect to lower the system cost by providing lower latency,
reduced overhead of packet data processing, and higher system bandwidth, all of which are key for wireless
interfaces. For more information, see the Serial RapidIO (SRIO) for KeyStone Devices User Guide (literature number
SPRUGW1).
7.26 General-Purpose Input/Output (GPIO)
7.26.1 GPIO Device-Specific Information
On the TMS320C6671, the GPIO peripheral pins GP[15:0] are also used to latch configuration pins. For more
detailed information on device/peripheral configuration and the C6671 device pin muxing, see ‘‘Device
Configuration’’ on page 64. For more information on GPIO, see the General Purpose Input/Output (GPIO) for

7.27 Semaphore2
The device contains an enhanced Semaphore module for the management of shared resources of the DSP C66x
CorePacs. The Semaphore enforces atomic accesses to shared chip-level resources so that the read-modify-write
sequence is not broken. The semaphore block has unique interrupts to each of the cores to identify when that core
has acquired the resource.
Semaphore resources within the module are not tied to specific hardware resources. It is a software requirement to
allocate semaphore resources to the hardware resource(s) to be arbitrated.
The Semaphore module supports 8 masters and contains 32 semaphores to be used within the system.
There are two methods of accessing a semaphore resource:
•
•
Direct Access: A core directly accesses a semaphore resource. If free, the semaphore will be granted. If not, the
semaphore is not granted.
Indirect Access: A core indirectly accesses a semaphore resource by writing it. Once it is free, an interrupt
notifies the CPU that it is available.
7.28 Emulation Features and Capability
7.28.1 Advanced Event Triggering (AET)
The TMS320C6671 device supports Advanced Event Triggering (AET). This capability can be used to debug
complex problems as well as understand performance characteristics of user applications. AET provides the
following capabilities:
•
Hardware Program Breakpoints: specify addresses or address ranges that can generate events such as halting
the processor or triggering the trace capture.
•
Data Watchpoints: specify data variable addresses, address ranges, or data values that can generate events
such as halting the processor or triggering the trace capture.
•
•
Counters: count the occurrence of an event or cycles for performance monitoring.
State Sequencing: allows combinations of hardware program breakpoints and data watchpoints to precisely
generate events for complex sequences.
For more information on AET, see the following documents:
•
Using Advanced Event Triggering to Find and Fix Intermittent Real-Time Bugs application report (literature
number SPRA753)
•
Using Advanced Event Triggering to Debug Real-Time Problems in High Speed Embedded Microprocessor
Systems application report (literature number SPRA387)
7.28.2 Trace
The C6671 device supports Trace. Trace is a debug technology that provides a detailed, historical account of
application code execution, timing, and data accesses. Trace collects, compresses, and exports debug information
for analysis. Trace works in real-time and does not impact the execution of the system.
For more information on board design guidelines for Trace Advanced Emulation, see the 60-Pin Emulation Header
Technical Reference (literature number SPRU655).

7.28.3 IEEE 1149.1 JTAG
The JTAG interface is used to support boundary scan and emulation of the device. The boundary scan supported
allows for an asynchronous TRST and only the 5 baseline JTAG signals (e.g., no EMU[1:0]) required for boundary
scan. Most interfaces on the device follow the Boundary Scan Test Specification (IEEE1149.1), while all of the SerDes
(SRIO and SGMII) support the AC-coupled net test defined in AC-Coupled Net Test Specification (IEEE1149.6).
It is expected that all compliant devices are connected through the same JTAG interface, in daisy-chain fashion, in
accordance with the specification. The JTAG interface uses 1.8-V LVCMOS buffers, compliant with the Power
Supply Voltage and Interface Standard for Nonterminated Digital Integrated Circuit Specification (EAI/JESD8-5).
7.28.3.1 IEEE 1149.1 JTAG Compatibility Statement
For maximum reliability, the C6671 DSP includes an internal pulldown (IPD) on the TRST pin to ensure that TRST
will always be asserted upon power up and the DSP's internal emulation logic will always be properly initialized
when this pin is not routed out. JTAG controllers from Texas Instruments actively drive TRST high. However, some
third-party JTAG controllers may not drive TRST high but expect the use of an external pullup resistor on TRST.
When using this type of JTAG controller, assert TRST to initialize the DSP after powerup and externally drive TRST
high before attempting any emulation or boundary scan operations.
