目前,微程序时序控制器的应用日益增多,微程序方式正在普及.一般地说,微程序时序控制器不同于非微程序时序控制器.非微程序时序控制器所完成的控制功能是通过组合门和触发器实现的.这些门和触发器多少按照随机的方式联接起来,产生需要的定时和控制信号.而微程序时序控制器则是根据控制对象的需要,把控制数据(微指令)编成程序存入存储器(微程序存储器).工作时时序控制对微程序存储器的访 At present, the application of the microprogramming timing controller is increasing day by day, and the microprogramming method is gaining popularity.Generally, the microprogramming timing controller is different from the non-microprogramming timing controller, and the control function performed by the non-microprogramming timing controller is by combining Gates, and flip-flops. These gates and flip-flops are connected in a random manner in a random manner to generate the required timing and control signals, and the microprogramming timing controller, based on the needs of the control object, encodes the control data (microinstructions) Into the program memory (micro-program memory). Working time sequence control of the micro-program memory visit
