基于微程序控制模型机的设计与实现

Design and Implementationof Model Machine Based on Microprogramming

本文实现了基于微程序控制的带移位运算的模型机,主要由运算模块,存储模块,控制模块和辅助模块组成,本系统主要完成加法、循环移位、跳转、输入、输出、读写存储器的微程序设计,以及双字和单字指令的读写功能。该设计便于对指令流和数据流的动态变化的理解,对学生巩固计算机组成原理理论的理解,整机各个组成部分如何协同工作具有积极的作用,对开拓自主实验和学习移位运算具有重要的实践意义。

In this paper, it implements the model machine with shift-operation based on microprogramming.It mainly composes ofarithmetic and logic unit（ALU）, storage module, controlled unit（CU） and auxiliary module.This system mainly completes the design of microprogrammindcluding the instruction of addition, circulating shift, jump, input, output, reading and writing memory, as well as the function of reading and writing single-byte or double-bytes instruction. Itis good for understanding of the dynamic change of the instruction stream and data flow, the theory of computer constitute principlefor students, how do the components of machine work together. It is of great practical significance to design self-determinationexperiment and study of shift operation.
