GENERAL DESCRIPTION
levels of prioritized internal and external interrupts, and a
faults and exceptions handler controlling internally and
externally generated faults.
The PACE1750A is a general purpose, single chip, 16-bit
CMOS microprocessor designed for high performance
floating point and integer arithmetic, with extensive real
timeenvironmentsupport. Itoffersavarietyofdatatypes,
includingbits, bytes, 16-bitand32-bitintegers, and32-bit
and48-bitfloatingpointnumbers. Itprovides13addressing
modes, including direct, indirect, indexed, based, based
indexed and immediate long and short, and it can access
2 MWords of segmented memory space (64 KWords
segments).
Themicroprocessorachievesveryhighthroughputof2.6
MIPS for a standard real time integer/floating point
instructionmixata40MHzclock. ItexecutesintegerAdd
in 0.1 µs, integer Multiply in 0.575 µs, Floating Point Add
in 0.7 µs, and Floating Point Multiply in 1.075 µs, for
register operands at a 40 MHz clock speed.
ThePACE1750Ausesasinglemultiplexed16-bitparallel
bus. Status signals are provided to determine whether
the processor is in the memory or I/O bus cycle, reading
and writing, and whether the bus cycle is for data or
instructions.
The PACE1750A offers a well-rounded instruction set
with 130 instruction types, including a comprehensive
integer,floatingpoint,integer-to-floatingpointandfloating
point-to-integer set, a variety of stack manipulation
instructions, high level language support instructions
such as Compare Between Bounds and Loop Control
Instructions. It also offers some unique instructions such
as vectored l/O, supports executive and user modes, and
providesanescapemechanismwhichallowsuser-defined
instructions using a coprocessor.
Thebasicbuscycleis4clockslong. ThePACE1750Awill
extend the cycle by insertion of wait states in the address
and data phases (in response to RDYA and RDYD
signals, repectively) and will hold the machine in HI-Z if
this CPU has not acquired the bus. A typical non-bus
cycle is three clocks long. However, variable length
cyclesareusedforsuchrepetitiveoperationsasmultiply,
divide, scale and normalize, reducing significantly the
numberofCPUCLOCKSperoperationstepandresulting
in very fast integer and floating point execution times.
The chip includes 16 general purpose registers, 8 other
user-accessible registers, and an array of real time
application support resources, such as 2 programmable
timers, a complete interrupt controller supporting 16

BUS ARBITRATION
Mnemonic
Name
Description
BUS REQ
Bus request
An active LOW output that indicates the CPU requires the bus. It
becomes inactive when the CPU has acquired the bus and started the
bus cycle.
BUS GNT
Bus grant
An active LOW input from an external arbiter that indicates the CPU
currently has the highest priority bus request. If the bus is not used and
not locked, the CPU may begin a bus cycle, commencing with the next
CPU clock. A HIGH level will hold the CPU in Hi-Z state (Bz), three-
stating the IB bus status lines (D/I, R/W, M/IO), strobes (STRBA,
STRBD), and all the other lines that go three-state when this CPU does
not have the bus.
BUS BUSY
Bus busy
Bus lock
An active LOW, bidirectional signal used to establish the beginning and
end of a bus cycle. The trailing edge (LOW-to-HIGH transition) is used
for sampling bits into the fault register. It is three-state in bus cycles not
assigned to this CPU. However, the CPU monitors the BUS BUSY line
for latching non-CPU bus cycle faults into the fault register.
BUS LOCK
An active low, bi-directional signal used to lock the bus for successive
buscycles. Duringnon-lockedbuscycles,theBUSLOCK signalmimics
the BUS BUSY signal. It is three-state during bus cycles not assigned to
the CPU. The following instructions will lock the bus: INCM, DECM, SB,
RB, TSB, SRM, STUB and STLB.

DMA EN
Direct memory
Access enable
An active HIGH output that indicates the DMA is enabled. It is
disabled when the CPU is initialized (reset) and can be enabled or
disabled under program control (I/O commands DMAE, DMAD).
An active HIGH output that is set when the CPU has successfully
completed the built-in self test in the initialization sequence. It can be
reset by the I/O command RNS.
NML PWRUP
Normal power up
SNEW
Start new
An active HIGH output that indicates a new instruction is about to start
executing in the next cycle.
TRIGO RST
