逻辑函数的展开与数据选择器（DST）的通用性

逻辑函数的展开与数据选择器（DST）的通用性 THE EXPANSION OF LOGIC FUNCTION AND THE UNIVERSALITY OF DATA SELECTORS（DST） 卢孝先 Lu Xiaoxian first-author 本文导出了逻辑函数的分组展开式,该式可看作是逻辑函数的积—和型标准表达式的推广,并为DST用作组合逻辑的通用组件提供了依据。同时,本文还给出了一种以DST为通用组件的组合逻辑设计方法——奇偶顺序法,该方法直观易行,简便快捷。 In this paper an expansion formula of logic function with respect to group-variable has been derived. The formula can be regarded as the extension of the canonical sum-of-products form of logic function, and provides the basis for using DST as an universal logic module. Meanwhile, this paper also gives a combinational logic design method using DST as universal logic module——Odd——Even Order Method. The method is straightfoward, easy to implement, simple, convenient, and fast in designing. 1981-01-01 2021-04-01 1
