应用 M IS 时序部件设计一般时序电路

本文提出把可同步激励的MSI时序部件当作一个多功能的复杂存储元件使用,并对计数型MSI与移位型MSI分别给出了它们的次态方程与激励表.此外,提出了应用这两种MSI时序部件设计一般时序电路的状态安排规则及设计程序.讨论表明,这种设计方法在本质上相当于对专用MSI时序部件的基本工作时序进行时序修改.

Design of General Sequential Circuits by Using MSI Sequential Elements

This paper proposes that a MSI sequential element which is synchronously excitable may be used as complicated memory element with multi-function. The next state equations and excitation tables of a counter-type MSI and a register-type MSI are presented. Furthermore, through a desingn example, the rules of state assignment and the design procedures by the use of these two MSI sequential elements are proposed here. The discussion shows this design method is essentially equivalent to a sequential modification to the basic sequence of a special MSI sequential element.
