摘　　要：异步电路的设计能够解决功耗、系统速度、时钟偏移等问题,成为当前VLSI研究的热点。文章提出了4级灰度LCD控制器异步电路的设计方案,通过异步控制以消除无效操作从而降低功耗,经验证平均功耗仅为同步电路的23.7%;异步电路还实现了部分显示和滚屏等功能,加快了系统响应速度。The design of asynchronous circuits is widely used in modem VLSI design, which is able to resolve the problems of power dissipation, system speed, clock skew, etc. A solution of asynchronous logic of 4 gray scale LCD controller is presented, which disables invalid operations to reduce power dissipation by asynchronous control. The results of the simulations show that the power dissipation on average is reduced to 23.7% compared with synchronous logic; asynchronous circuits also implement the function of partial display and rolling screen, speed up the response of system.
