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
