TMS320C6203B, TMS320C6203C
FIXED-POINT DIGITAL SIGNAL PROCESSORS
SPRS086F – JANUARY 1999 – REVISED SEPTEMBER 2001
description
The TMS320C6203B and TMS320C6203C devices are part of the TMS320C62x fixed-point DSP generation
in the TMS320C6000 DSP platform. The C62x DSP devices are based on the high-performance, advanced
VelociTI very-long-instruction-word (VLIW) architecture developed by Texas Instruments (TI), making these
DSPs an excellent choice for multichannel and multifunction applications.
The TMS320C62x DSP offers cost-effective solutions to high-performance DSP-programming challenges.
The TMS320C6203B/03C has a performance capability of up to 2400 MIPS at a clock rate of 300 MHz. The
C6203B/03C DSP possesses the operational flexibility of high-speed controllers and the numerical capability
of array processors. This processor has 32 general-purpose registers of 32-bit word length and eight highly
independent functional units. The eight functional units provide six arithmetic logic units (ALUs) for a high
degree of parallelism and two 16-bit multipliers for a 32-bit result. The C6203B/03C can produce two
multiply-accumulates (MACs) per cycle for a total of 600 million MACs per second (MMACS). The C6203B/03C
DSP also has application-specific hardware logic, on-chip memory, and additional on-chip peripherals.
The C6203B/03C device program memory consists of two blocks, with a 256K-byte block configured as
memory-mapped program space, and the other 128K-byte block user-configurable as cache or
memory-mapped program space. Data memory for the C6203B/03C consists of two 256K-byte blocks of RAM.
The C6203B/03C device has a powerful and diverse set of peripherals. The peripheral set includes three
multichannel buffered serial ports (McBSPs), two general-purpose timers, a 32-bit expansion bus (XBus) that
offers ease of interface to synchronous or asynchronous industry-standard host bus protocols, and a glueless
32-bit external memory interface (EMIF) capable of interfacing to SDRAM or SBSRAM and asynchronous
peripherals.
The C62x devices have a complete set of development tools which includes: a new C compiler, an assembly
optimizer to simplify programming and scheduling, and a Windows debugger interface for visibility into source
code execution.

SPRS086F – JANUARY 1999 – REVISED SEPTEMBER 2001
CPU (DSP core) description
The CPU fetches VelociTI advanced very-long instruction words (VLIW) (256 bits wide) to supply up to eight
32-bit instructions to the eight functional units during every clock cycle. The VelociTI VLIW architecture
features controls by which all eight units do not have to be supplied with instructions if they are not ready to
execute. The first bit of every 32-bit instruction determines if the next instruction belongs to the same execute
packet as the previous instruction, or whether it should be executed in the following clock as a part of the next
execute packet. Fetch packets are always 256 bits wide; however, the execute packets can vary in size. The
variable-length execute packets are a key memory-saving feature, distinguishing the C62x CPU from other
VLIW architectures.
The CPU features two sets of functional units. Each set contains four units and a register file. One set contains
functional units .L1, .S1, .M1, and .D1; the other set contains units .D2, .M2, .S2, and .L2. The two register files
eachcontain1632-bitregistersforatotalof32general-purposeregisters. Thetwosetsoffunctionalunits, along
with two register files, compose sides A and B of the CPU [see the functional and CPU (DSP core) block diagram
and Figure 1]. The four functional units on each side of the CPU can freely share the 16 registers belonging to
that side. Additionally, each side features a single data bus connected to all the registers on the other side, by
which the two sets of functional units can access data from the register files on the opposite side. While register
access by functional units on the same side of the CPU as the register file can service all the units in a single
clock cycle, register access using the register file across the CPU supports one read and one write per cycle.
Another key feature of the C62x CPU is the load/store architecture, where all instructions operate on registers
(as opposed to data in memory). Two sets of data-addressing units (.D1 and .D2) are responsible for all data
transfers between the register files and the memory. The data address driven by the .D units allows data
addresses generated from one register file to be used to load or store data to or from the other register file. The
C62x CPU supports a variety of indirect addressing modes using either linear- or circular-addressing modes
with 5- or 15-bit offsets. All instructions are conditional, and most can access any one of the 32 registers. Some
registers, however, are singled out to support specific addressing or to hold the condition for conditional
instructions (if the condition is not automatically “true”). The two .M functional units are dedicated for multiplies.
The two .S and .L functional units perform a general set of arithmetic, logical, and branch functions with results
available every clock cycle.
The processing flow begins when a 256-bit-wide instruction fetch packet is fetched from a program memory.
The 32-bit instructions destined for the individual functional units are “linked” together by “1” bits in the least
significant bit (LSB) position of the instructions. The instructions that are “chained” together for simultaneous
execution (up to eight in total) compose an execute packet. A “0” in the LSB of an instruction breaks the chain,
effectively placing the instructions that follow it in the next execute packet. If an execute packet crosses the
256-bit-wide fetch-packet boundary, the assembler places it in the next fetch packet, while the remainder of the
current fetch packet is padded with NOP instructions. The number of execute packets within a fetch packet can
vary from one to eight. Execute packets are dispatched to their respective functional units at the rate of one per
clock cycle and the next 256-bit fetch packet is not fetched until all the execute packets from the current fetch
packet have been dispatched. After decoding, the instructions simultaneously drive all active functional units
for a maximum execution rate of eight instructions every clock cycle. While most results are stored in 32-bit
registers, they can be subsequently moved to memory as bytes or half-words as well. All load and store
instructions are byte-, half-word, or word-addressable.

memory map summary
Table 2 shows the memory map address ranges of the C6203B/03C device. The C6203B/03C device has the
capability of a MAP 0 or MAP 1 memory block configuration. These memory block configurations are set up at
reset by the boot configuration pins (generically called BOOTMODE[4:0]). For the C6203B/03C device, the
BOOTMODE configuration is handled, at reset, by the expansion bus module (specifically XD[4:0] pins). For
more detailed information on the C6203B/03C device settings, which include the device boot mode
configuration at reset and other device-specific configurations, see the Boot Configuration section and the Boot
Configuration Summary table of the TMS320C6000 Peripherals Reference Guide (literature number
SPRU190).

DMA synchronization events
The C6203B/C6203C DMA supports up to four independent programmable DMA channels, plus an auxiliary
channel used for servicing the HPI module. The four main DMA channels can be read/write synchronized based
on the events shown in Table 3. Selection of these events is done via the RSYNC and WSYNC fields in the
Primary Control registers of the specific DMA channel. For more detailed information on the DMA module,
associated channels, and event-synchronization, see the Direct Memory Access (DMA) Controller chapter of
the TMS320C6000 Peripherals Reference Guide (literature number SPRU190).

interrupt sources and interrupt selector
The C62x DSP core supports 16 prioritized interrupts, which are listed in Table 4. The highest-priority interrupt
is INT_00 (dedicated to RESET) while the lowest-priority interrupt is INT_15. The first four interrupts
(INT_00–INT_03) are non-maskable and fixed. The remaining interrupts (INT_04–INT_15) are maskable and
default to the interrupt source specified in Table 4. The interrupt source for interrupts 4–15 can be programmed
by modifying the selector value (binary value) in the corresponding fields of the Interrupt Selector Control
registers: MUXH (address 0x019C0000) and MUXL (address 0x019C0004).

development support
TI offers an extensive line of development tools for the TMS320C6000 DSP platform, including tools to
evaluate the performance of the processors, generate code, develop algorithm implementations, and fully
integrate and debug software and hardware modules.
The following products support development of C6000 DSP-based applications:
Software Development Tools:
Code Composer Studio Integrated Development Environment (IDE) including Editor
C/C++/Assembly Code Generation, and Debug plus additional development tools
Scalable, Real-Time Foundation Software (DSP/BIOS ), which provides the basic run-time target software
needed to support any DSP application.
Hardware Development Tools:
Extended Development System (XDS ) Emulator (supports C6000 DSP multiprocessor system debug)
EVM (Evaluation Module)
The TMS320 DSP Development Support Reference Guide (SPRU011) contains information about
development-support products for all TMS320 DSP family member devices, including documentation. See
thisdocumentforfurtherinformationonTMS320 DSPdocumentationoranyTMS320 DSPsupportproducts
from Texas Instruments. An additional document, the TMS320 Third-Party Support Reference Guide
(SPRU052), contains information about TMS320 DSP-related products from other companies in the industry.
To receive TMS320 DSP literature, contact the Literature Response Center at 800/477-8924.
For a complete listing of development-support tools for the TMS320C6000 DSP platform, visit the Texas
Instruments web site on the Worldwide Web at http://www.ti.com uniform resource locator (URL) and select
“Find Development Tools”. For device-specific tools, under “Semiconductor Products” select “Digital Signal

device and development-support tool nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all
TMS320 DSP devices and support tools. Each TMS320 DSP commercial family member has one of three
prefixes: TMX, TMP, or TMS. Texas Instruments recommends two of three possible prefix designators for
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
TMP
TMS
Experimental device that is not necessarily representative of the final device’s electrical
specifications
Final silicon die that conforms to the device’s electrical specifications but has not completed
quality and reliability verification
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 against 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. TexasInstrumentsrecommendsthatthesedevicesnotbeusedinanyproductionsystembecausetheir
expected end-use failure rate still is undefined. Only qualified production devices are to be used.
TI device nomenclature also includes a suffix with the device family name. This suffix indicates the package type
(for example, GLS), the temperature range (for example, blank is the default commercial temperature range),
and the device speed range in megahertz (for example, -300 is 300 MHz).
Figure 4 provides a legend for reading the complete device name for any member of the TMS320C6000 DSP
platform. For the C6203B/03C device orderable part numbers (P/Ns), see the Texas Instruments web site on
theWorldwidewebathttp://www.ti.comURL, orcontactthenearestTIfieldsalesoffice, orauthorizeddistributor.

clock PLL
Most of the internal C6203B/03C clocks are generated from a single source through the CLKIN pin. This source
clock either drives the PLL, which multiplies the source clock in frequency to generate the internal CPU clock,
or bypasses the PLL to become the internal CPU clock.
To use the PLL to generate the CPU clock, the external PLL filter circuit must be properly designed. Figure 5,
and Table 6 through Table 8 show the external PLL circuitry for either x1 (PLL bypass) or x4 PLL multiply modes.
Figure 6 shows the external PLL circuitry for a system with ONLY x1 (PLL bypass) mode.
To minimize the clock jitter, a single clean power supply should power both the C6203B/03C device and the
external clock oscillator circuit. Noise coupling into PLLF directly impacts PLL clock jitter. The minimum CLKIN
rise and fall times should also be observed. For the input clock timing requirements, see the input and output
clocks electricals section. Table 5 lists some examples of compatible CLKIN external clock sources:

NOTES: A. Keep the lead length and the number of vias between pin PLLF, pin PLLG, R1, C1, and C2 to a minimum. In addition, place all PLL
components (R1, C1, C2, C3, C4, and EMI Filter) as close to the C6000 DSP device as possible. Best performance is achieved
with the PLL components on a single side of the board without jumpers, switches, or components other than the ones shown.
B. For reduced PLL jitter, maximize the spacing between switching signals and the PLL external components (R1, C1, C2, C3, C4,
and the EMI Filter).

CLKMODE x1, x4, x6, x8, and x12 apply to the GNY device. The GNZ device is restricted to x1, x4, x8, and x12 multiply factors.
The PLL component selection for the C6203C device is specified as a range because the C6203C device can use the same PLL components
as the C6203B, C6202/02B, or C6204 devices.
For the C6203C device, the R1, C1, and C2 components are not required; however, for the benefit of being able to migrate between the C6203B,
C6202/02B, and C6204 devices, it is recommended that these components be installed.

power-supply sequencing
TI DSPs do not require specific power sequencing between the core supply and the I/O supply. However,
systems should be designed to ensure that neither supply is powered up for extended periods of time if the other
supply is below the proper operating voltage.
system-level design considerations
System-level design considerations, such as bus contention, may require supply sequencing to be
implemented. In this case, the core supply should be powered up at the same time as, or prior to (and powered
down after), the I/O buffers. This is to ensure that the I/O buffers receive valid inputs from the core before the
output buffers are powered up, thus, preventing bus contention with other chips on the board.
power-supply design considerations
For systems using the C6000 DSP platform of devices, the core supply may be required to provide in excess
of 2 A per DSP until the I/O supply is powered up. This extra current condition is a result of uninitialized logic
within the DSP(s) and is corrected once the CPU sees an internal clock pulse. With the PLL enabled, as the
I/O supply is powered on, a clock pulse is produced stopping the extra current draw from the supply. With the
PLL disabled, as many as five external clock cycle pulses may be required to stop this extra current draw. A
normal current state returns once the I/O power supply is turned on and the CPU sees a clock pulse. Decreasing
the amount of time between the core supply power up and the I/O supply power up can minimize the effects
of this current draw.
A dual-power supply with simultaneous sequencing, such as available with TPS563xx controllers or PT69xx
plug-in power modules, can be used to eliminate the delay between core and I/O power up [see the Using the
TPS56300 to Power DSPs application report (literature number SLVA088)]. A Schottky diode can also be used
to tie the core rail to the I/O rail, effectively pulling up the I/O power supply to a level that can help initialize the
logic within the DSP.
Core and I/O supply voltage regulators should be located close to the DSP (or DSP array) to minimize
inductance and resistance in the power delivery path. Additionally, when designing for high-performance
applications utilizing the C6000 platform of DSPs, the PC board should include separate power planes for
core, I/O, and ground, all bypassed with high-quality low-ESL/ESR capacitors.

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 utilizing the available I/O buffer information specification
(IBIS) models to analyze the timing characteristics correctly. 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
fromtheexternaldevicetotheDSP. Thisround-tripdelaytendstonegativelyimpacttheinputsetuptimemargin,
but also tends to improve the input hold time margins (see Table 10 and Figure 10).
Figure 10 represents a general transfer between the DSP and an external device. The figure also represents
board route delays and how they are perceived by the DSP and the external device.

‡
To ensure data setup time, simply program the strobe width wide enough. ARDY is internally synchronized. If ARDY does meet setup or hold
time, it may be recognized in the current cycle or the next cycle. Thus, ARDY can be an asynchronous input.
RS = Read Setup, RST = Read Strobe, RH = Read Hold, WS = Write Setup, WST = Write Strobe, WH = Write Hold. These parameters are
programmed via the EMIF CE space control registers.
P = 1/CPU clock frequency in ns. For example, when running parts at 300 MHz, use P = 3.33 ns.
The sum of RS and RST (or WS and WST) must be a minimum of 4 in order to use ARDY input to extend strobe width.

P = 1/CPU clock frequency in ns. For example, when running parts at 300 MHz, use P = 3.33 ns.
EMIF Bus consists of CE[3:0], BE[3:0], ED[31:0], EA[21:2], ARE, AOE, AWE, SDCAS/SSADS, SDRAS/SSOE, SDWE/SSWE, and SDA10.
All pending EMIF transactions are allowed to complete before HOLDA is asserted. The worst case for this is an asynchronous read or write with
external ARDY used or a minimum of eight consecutive SDRAM reads or writes when RBTR8 = 1. If no bus transactions are occurring, then the
minimum delay time can be achieved. Also, bus hold can be indefinitely delayed by setting NOHOLD = 1.

This parameter applies to CLKMODE x1 when CLKIN is stable, and applies to CLKMODE x4, x6, x7, x8, x9, x10, and x11 when CLKIN and PLL
are stable for C6203B. And applies to CLKMODE x4, x6, x8, and x12 when CLKIN and PLL are stable for C6203C.
This parameter applies to CLKMODE x4, x6, x7, x8, x9, x10, and x11 only (it does not apply to CLKMODE x1) for C6203B. This parameter applies
to CLKMODE x4, x6, x8, and x12 only (it does not apply to CLKMODE x1) for C6203C. The RESET signal is not connected internally to the clock
PLL circuit. The PLL, however, may need up to 250 µs to stabilize following device power up or after PLL configuration has been changed. During
that time, RESET must be asserted to ensure proper device operation. See the Clock PLL section for PLL lock times.
XD[31:0] are the boot configuration pins during device reset.

To ensure data setup time, simply program the strobe width wide enough. XRDY is internally synchronized. If XRDY does meet setup or hold
time, it may be recognized in the current cycle or the next cycle. Thus, XRDY can be an asynchronous input.
RS = Read Setup, RST = Read Strobe, RH = Read Hold, WS = Write Setup, WST = Write Strobe, WH = Write Hold. These parameters are
programmed via the XBUS XCE space control registers.
§
¶
P = 1/CPU clock frequency in ns. For example, when running parts at 300 MHz, use P = 3.3 ns.
The sum of RS and RST (or WS and WST) must be a minimum of 4 in order to use XRDY input to extend strobe width.

CLKRP = CLKXP = FSRP = FSXP = 0. If the polarity of any of the signals is inverted, then the timing references of that signal are also inverted.
P = 1/CPU clock frequency in ns. For example, when running parts at 300 MHz, use P = 3.3 ns.
The maximum bit rate for the C6203B/03C device is 100 Mbps or CPU/2 (the slower of the two). Care must be taken to ensure that the AC timings
specified in this data sheet are met. The maximum bit rate for McBSP-to-McBSP communications is 100 MHz; therefore, the minimum CLKR/X
clock cycle is either twice the CPU cycle time (2P), or 10 ns (100 MHz), whichever value is larger. For example, when running parts at 300 MHz
(P = 3.3 ns), use 10 ns as the minimum CLKR/X clock cycle (by setting the appropriate CLKGDV ratio or external clock source). When running
parts at 100 MHz (P = 10 ns), use 2P = 20 ns (50 MHz) as the minimum CLKR/X clock cycle. The maximum bit rate for McBSP-to-McBSP
communications applies when the serial port is a master of the clock and frame syncs (with CLKR connected to CLKX, FSR connected to FSX,
CLKXM = FSXM = 1, and CLKRM = FSRM = 0) in data delay 1 or 2 mode (R/XDATDLY = 01b or 10b) and the other device the McBSP
communicates to is a slave.
¶
The minimum CLKR/X pulse duration is either (P–1) or 4 ns, whichever is larger. For example, when running parts at 300 MHz (P = 3.3 ns), use
4 ns as the minimum CLKR/X pulse duration. When running parts at 100 MHz (P = 10 ns), use (P–1) = 9 ns as the minimum CLKR/X pulse
duration.

CLKRP = CLKXP = FSRP = FSXP = 0. If the polarity of any of the signals is inverted, then the timing references of that signal are also inverted.
Minimum delay times also represent minimum output hold times.
P = 1/CPU clock frequency in ns. For example, when running parts at 300 MHz, use P = 3.3 ns.
The maximum bit rate for the C6203B/03C device is 100 Mbps or CPU/2 (the slower of the two). Care must be taken to ensure that the AC timings
specified in this data sheet are met. The maximum bit rate for McBSP-to-McBSP communications is 100 MHz; therefore, the minimum CLKR/X
clock cycle is either twice the CPU cycle time (2P), or 10 ns (100 MHz), whichever value is larger. For example, when running parts at 300 MHz
(P = 3.3 ns), use 10 ns as the minimum CLKR/X clock cycle (by setting the appropriate CLKGDV ratio or external clock source). When running
parts at 100 MHz (P = 10 ns), use 2P = 20 ns (50 MHz) as the minimum CLKR/X clock cycle. The maximum bit rate for McBSP-to-McBSP
communications applies when the serial port is a master of the clock and frame syncs (with CLKR connected to CLKX, FSR connected to FSX,
CLKXM = FSXM = 1, and CLKRM = FSRM = 0) in data delay 1 or 2 mode (R/XDATDLY = 01b or 10b) and the other device the McBSP
communicates to is a slave.
