20, 25, and 30 MHz operation over the Military

Temperature Range

Available in:

- 68-Lead Quad Pack (Leaded Chip Carrier) with

Optional Gull Wing

Extensive Error and Fault Management and

Interrupt Capability

GENERAL DESCRIPTION

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

levels of prioritized internal and external interrupts, and a

faults and exceptions handler controlling internally and

externally generated faults.

ThePACE1750Aisageneralpurpose,application-proven,

single chip, 16-bit CMOS microprocessor designed for

high performance floating point and integer arithmetic,

with extensive real time environment support. It offers a

variety of data types, including bits, bytes, 16-bit and 32-

bit integers, and 32-bit and 48-bit floating point numbers.

Itprovides13addressingmodes,includingdirect,indirect,

indexed, based, based indexed and immediate long and

short,anditcanaccess2MWordsofsegmentedmemory

space (64 KWords segments without use of a MIL-STD-

1750A MMU).

TheP1750Ausesasinglemultiplexed16-bitparallelbus.

Status signals are provided to determine whether the

processor is in the memory or I/O bus cycle, reading and

writing,andwhetherthebuscycleisfordataorinstructions.

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. The instruction set is

fully compliant with MIL-STD-1750A.

The basic bus cycle is 4 clocks long. The P1750A will

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.
