一、前言国外32位微型计算机在迅猛发展,美国、日本、英国等国在全力以赴地研制或不断改进32位微机芯片和开发32位微机系统:一种片上高速缓冲存贮器(on—chip CACHE)和存贮器管理部件(MMU)已经在32位微机芯片开发中诞生,它的诞生,对于提高整个微机性能极为重要,它有效地支持了处理机处理高速数据交换及大容量信息贮存的要求。INTEL80386及Z80000均已实现了上述功能,Motorola公司的研制计划中不久也将推出在芯片上含

I. INTRODUCTION Foreign 32-bit microcomputers are booming. The United States, Japan, the United Kingdom and other countries are making every effort to develop or continuously improve 32-bit microcomputers and develop 32-bit microcomputers: an on- chip CACHE and memory management unit (MMU) have been born in the development of 32-bit microcomputer chips. It was born to be extremely important for improving the overall PC performance. It effectively supports the processor to handle high-speed data exchange and large-capacity message storage Request. INTEL80386 and Z80000 have achieved the above functions, Motorola’s development plan will soon be introduced on the chip with
