多输出逻辑函数简化方法的探讨

A Brief Survey of the Simplification of Multi-Output Logical Function

本文提出一种用相关乘积卡诺图对多输出逻辑函数进行简化的新方法,即用一张相关乘积卡诺图便可求出所有的公有质蕴涵项,在单个函数的卡诺图上可求出最佳简化结果.文中论述了它的原理和使用方法,给出了简化步骤和优化准则,介绍了这种方法在设计中规模集成电路中的应用.

The principle and application of a new method for the simplification of multi-output logical function is described, a K-map of correlation product is used for finding all common quality implication terms. On each individual function K-map, simplified optimal results can then be obtained. The procedures and optimization criteria are given. An example of design of a medium-sized IC with multi-output is given for illustration,
