微程序
微程序控制(简称微码控制)的基本思路是:用微指令产生微操作命令,用若干条微指令组成一段微程序实现一条机器指令的功能(为了加以区别,将前面所讲的指令称为机器指令)。设机器指令M执行时需要三个阶段,每个阶段需要发出如下命令:阶段一发送K1、K8命令,阶段二发送K0、K2、K3、K4命令,阶段三发送K9命令。当将第一条微指令送到微指令寄存器时,微指令寄存器的K1和K8为1,即发出K1和K8命令,该微指令指出下一条微指令地址为00101,从中取出第二条微指令,送到微指令寄存器时将发出K0、K2、K3、K4命令,接下来是取第三条微指令,发K9命令。
微程序控制器的组成:
1、控制存储器(contmlMemory)用来存放各机器指令对应的微程序。译码器用来形成机器指令对应的微程序的入口地址。当将一条机器指令对应的微程序的各条微指令逐条取出,并送到微指令寄存器时,其微操作命令也就按事先的设计发出,因而也就完成了一条机器指令的功能。对每一条机器指令都是如此。
2、微指令的宽度直接决定了微程序控制器的宽度。为了简化控制存储器,可采取一些措施来缩短微指令的宽度。如采用字段译码法一级分段译码。显然,微指令的控制字段将大大缩短。,一些要同时产生的微操作命令不能安排在同一个字段中。为了进一步缩短控制字段,还可以将字段译码设计成两级或多级。
