摘　　要：介绍了一个低功耗嵌入式微控制器的电路结构及其VLSI的实现,该芯片利用EDA辅助设计实现了多时钟系统、哈佛结构、两级流水线结构以及内置液晶驱动电路,其指令集采用了类似通用八位机PIC16C5X的精简指令集。通过采用各种有效的措施,在0.5μm的CMOS工艺条件下,其功耗大大降低。The circuit structure and its VLSI design and implementation of a low power embedded microcontroller is presented. Taking advantage of EDA, we design the chip which has the multi-clock system, Ha Vard structure and two pipeline stages, and achieve a LCD driver circuit within the chip. Its instruction set adopt is reduced to like that of universal 8 - bit PIC16C5X. Fabricating the microcontroller in 0.5 μm CMOS technology, its power dissipation decreased enormously through some effective methods.
