摘　　要：介绍了一个采用异步电路设计的低功耗微控制器的电路结构及其 VL SI的实现 .该设计利用异步电路具有的低功耗特性 ,用异步逻辑设计并实现了一个 8位低功耗微控制器 .该微控制器与用传统同步方法设计 PIC16 C6 1的指令集兼容 ,功能相仿 ,在 CHARTERED0 .6 μm的工艺条件下 ,平均功耗只有 PIC16 C6 1的 16 % .A novel VLSI design and implementation of a low power 8 bit microcontroller using asynchronous logic is proposed.Taking advantage of the low power potential of asynchronous logic,the 2 stage pipelined MCU is carefully designed by chosing proper architecture as well as suitable asynchronous signal protocols that include a combination of a specific 'completion detection method' and 'matching delay method'.Other low power design techniques such as 'Gating Clock' are also applied to the design.Using synchronous design flow and standard cell library facilitates the asynchronous VLSI design and circuit implementation.Fabricated in Chartered 0 6μm CMOS technology,this power of asynchronous MCU,from simulation on power dissipation,would be only 16% of power dissipation of the conventionally designed PIC16C61,which shares the same instruction set and function as the designed MCU.
