随着大规模集成电路LSI 的出现,可以采用微处理机及其控制程序组成数字系统。从而代替使用门、触发器等构成数字系统的传统设计方法。本文介绍了采用微处理机的数字系统设计的一般过程。最后,以设计数字时钟为例说明过种方法。 With the advent of LSIs, microprocessors and their control programs can be used to form digital systems. Instead of using doors, triggers and other digital systems constitute the traditional design method. This article describes the general process of designing digital systems using microprocessors. Finally, the design of digital clock as an example of a kind of method.
