This paper discusses implementation of optimization of single output combinational logic functions using single board computers. Features of the developed program are less superfluous items by improving the covering method and less memory capacity requirement by using machine-language and careful porgraming. The firmware of this program is able to solve many practical problems so that it can be used as an useful tool for logic design or an interesting practice for teaching purpose. 本文讨论了单输出组合逻辑优化在单板机上的实现。所编程序通过改进覆盖方法,减少了冗余项;使用机器语言和精心编排程序,大大压缩了存贮容量。该程序固化后可方便地解决实用问题,并成为逻辑设计工作者的良好工具和有意义的教学实验内容。 A technique is presented for the synthesis of n-variable combinational logic function with multiplexer universal logic modules, which may be implemented rapidly and efficiently without using Kaunaugh map and complex operations. The method is based on a cubic decomposition map of residual logic function. Examples are given showing its use. It is found that the method is very convennt. 利用MUX级联网络实现多变量逻辑函数时,为求得最简的级联系统,本文提出了利用剩余函数立方图求取变量划分的快速方法。该法无需借助卡诺图,也不需要进行复杂的运算。结果表明,该法行之有效而且十分方便。 Dynamic max—covering method for simplifying combinational logic functions is presented in this paper.The method is simple,straightforward in processing,and strict in formality.It will be convinient for both observation and computer programming. 本文提出组合逻辑函数简化的动态极大复盖法。此法概念简单,手续简便,形势化强,既适用于观察法,更便于用计算机程序实现。
