NS32GX32-20/NS32GX32-25/NS32GX32-30

High-Performance 32-Bit Embedded System Processor

General Description

The NS32GX32 is a high-performance 32-bit embedded

Features

Software compatible with the Series 32000 family

system processor in the Series 32000 family. It is software

compatible with the previous microprocessors in the family

but with a greatly enhanced internal implementation.

32-bit architecture and implementation

4-GByte uniform addressing space

4-Stage instruction pipeline

The NS32GX32 integrates more than 320,000 transistors

fabricated in a 1.25 mm double-metal CMOS technology.

The advanced technology and mainframe-like design of the

device enable it to achieve peak performance of 15 million

instructions per second.

512-Byte on-chip instruction cache

1024-Byte on-chip data cache

High-performance bus

Ð Separate 32-bit address and data lines

Ð Burst mode memory accessing

Ð Dynamic bus sizing

The high-performance specifications are the result of a four-

stage instruction pipeline, on-chip instruction and data

caches, and a significantly increased clock frequency. In ad-

dition, the system interface provides optimal support for ap-

plications spanning a wide range, from low-cost, real-time

controllers to highly sophisticated, embedded systems.

Floating-point support via the NS32381

1.25 mm double-metal CMOS technology

175-pin PGA package

In addition to generally improved performance, the

NS32GX32 offers much faster interrupt service and task

switching for real-time applications.
