MA^M3^A1³7¹5⁷⁵0⁰

High Performance MIL-STD-1750 Microprocessor

Replaces July 2002 version, DS3748-8.1

DS3748-8.2 Feb 2006 (LN24435)

The Dynex Semiconductor MA31750 is a single-chip

microprocessor that implements the full MIL-STD-1750A

instruction set architecture, or Option 2 of Draft MIL-STD-

1750B. The processor executes all mandatory instructions and

many optional features are also included. Interrupts, fault

handling, memory expansion, Console, timers A and B, and

their related optional instructions are also supported in full

accordance with MIL-STD-1750.

The MA31750 offers a considerable performance increase

over the existing MAS281. This is achieved by using a 32-bit

internal bus structure with a 24 x 24 bit multiplier and 32-bit

ALU. Other performance-enhancing features include a 32-bit

shift network, a multi-port register file and a dedicated address

calculation unit.

The MA31750 has on-chip parity generation and checking

to enhance system integrity. A comprehensive built-in self-test

has also been incorporated, allowing processor functionality to

be verified at any time.

Console operation is supported through a parallel interface

using command/data registers in l/O space. Several discrete

output signals are produced to minimise external logic.

Control signals are also provided to allow inclusion of the

MA31750 into a multiprocessor or DMA system.

The processor can directly access 64KWords of memory in

full accordance with MIL-STD-1750A. This increases to

1MWord when used with the optional MA31751 memory

management unit (MMU). 1750B mode allows the system to

be expanded to 8MWord with the MMU.
