用蕴涵关系化简多输出逻辑函数

本文提出利用多输出逻辑函数之间的蕴涵关系,化简多输出逻辑函数的方法。这一方法能使多输出逻辑函数的总最小项数目减少,公有的本原蕴涵项的数目增多。这一化简法,较适合于中、大规范集成逻辑组件的综合。文中,通过具体例子将该法同常规化简法作了比较。最后,指出了这一化简法的局限性和有待进一步研究的问题。

The Application of the of Concept of Implication to Minimize Mutiple-output Logical Functions

In this paper a method for combined minimization of mutiple-output logical function is presented,it is shown that the effort required in minimization for mutiple-output logical functions is reduced when the implication among the logical functions is considered. The method is able to reduce the number minterms and increase the number of prine-implicants of mutiple-output functions. The paper describes the concept of implication among the mutiple-output logical functions and the method, using the concept for minimization mutiple-output logical functions. It also points out the limitation of the method and the work for the future.
