NS32CG160-15/NS32CG160-20/NSC32CG160-25

32-Bit Integrated System Processor

General Description

Features

Software compatible with the NS32CG16 and other em-

bedded system processors

The NS32CG160 is a highly-integrated member of the Se-

ries 32000/EP^TMfamily of National’s Embedded System

Processors^TMspecifically optimized for office imaging pe-

ripherals.

32-bit architecture and implementation

Special support for graphics applications

Ð On-chip BITBLT processing unit supports very fast

BITBLT operations

Ð 18 graphics instructions

Ð Binary compression/expansion capability for font

storage using RLL encoding

Ð Pattern magnification

The NS32CG160 provides a 16 Mbyte linear external ad-

dress space and a 16-bit external data bus. The CPU core

incorporates a 32-bit ALU and instruction pipeline, an 8-byte

prefetch queue and a 16 x 16-bit hardware multiplier.

Integrated on the same chip with the CPU is also a 2-chan-

nel DMA controller, a 16-function BitBLT Processing Unit

(BPU), a 15-level Interrupt Control Unit (ICU) and 3 pro-

grammable 16-bit timers.

Ð Interface to external BITBLT processing units for

multiple bitplane/color applications

On-chip clock generator

The on-chip hardware multiplier considerably enhances the

multiply instruction performance over its predecessors mak-

ing it better for graphics data calculations, such as outline

fonts.

Three on-chip programmable 16-bit timers

Two on-chip DMA channels with transfer rates up to

8 Mbyte/sec

On-chip Interrupt Control Unit provides 15 levels of pri-

oritized interrupts

The NS32CG160 capabilities can be expanded by using an

external floating point unit (FPU) which directly interfaces to

the NS32CG160 using the slave protocol. The CPU-FPU

cluster features high speed execution of the floating-point

instructions.

Floating-point support via the NS32081 or NS32181

On-chip hardware multiplier

Optimal interface to large memory arrays via the

NS32CG821 and the DP84xx family of DRAM control-

lers

The power and programmability of the 32-bit CPU Core

combined with the I/O peripherals generally found in micro-

controllers make the NS32CG160 an ideal single chip solu-

tion for embedded applications.

Fast interrupt service and task switching for real-time

applications

Power save mode

High-speed CMOS technology

84-pin PLCC package
