一、引言微程序控制是在计算机与其他数字控制系统中常用的一种控制方式。微程序设计是广为流行的逻辑设计方法。我们对微程序控制计算机及其他数字控制装置的考察表明,它们同用经典法进行逻辑设计的计算机及控制装置的一个重大差别是在组成上拥有控制存贮器。众所周知,在计算机系统中除了低 I. INTRODUCTION Microprogram control is a commonly used control method in computers and other digital control systems. Microprogramming is a popular method of logic design. Our examination of microprogramming computers and other digital control devices shows that one of the major differences between them and the computer and control devices that are logically designed using classical methods is the compositional control memory. As we all know, in addition to low in the computer system
