设计包括计算机在内的自动控制装置,除采用组合逻辑设计方法外,目前比较流行、且愈来愈为人们重视的方法,是微程序设计方法。该方法的控制存贮器是微程序控制器的关键设备。本文阐述它在微程序控制数字系统中的作用与地位;通过列举若干类型的控存,对其发展、原理与特点作了评价;并以较大篇幅论述了采用小规模组件的直控法微程序设计和采用PLA的微控器逻辑结构及其存贮信息的效率。文中所述的不同控存对微控器结构的影响,以及对控存方案的选择意见,可供设计时参考。
Design automatic control devices, including computers, in addition to the use of combinational logic design method, the more popular, and more and more people pay attention to the method is a micro-programming method. The method’s control memory is the key device of the microprogram controller. This article describes its role and position in the digital control system of microprogramming; evaluates its development, principle and characteristics by enumerating several types of control memory; and discusses in large part the direct control method using small-scale components Program Design and Implementation of PLA’s Microcontroller Logic Architecture and Efficiency of Storing Information. The different control described in the text on the micro-controller structure, as well as the choice of control options for the memory design, design reference.
