具有相同输入变量而有多个输出的逻辑网络的化简,如果只是孤立的将单个输出函数化简,然后直接拼在一起,有时并不能保证这个多输出网络为最简。因为对于这种网络有时存在能够共享的部分。为使多输出网络得到最简化表达式,通常使用的Q—M法或卡诺图法,都相当复杂。本文介绍的化简方法,是将卡诺图法作了较大的改进,使化简过程更加简便。
The simplification of logical networks with the same input variables and multiple outputs can sometimes not guarantee that this multiple output network is minimalistic if only a single output function is reduced in isolation and then spelled together directly. Because sometimes there is a part that can be shared for this kind of network. The most commonly used Q-M or Karnaugh map methods are quite complicated for the most simplified expression of multiple output networks. The simplification method introduced in this paper is that the Karnaugh map method has been greatly improved, making the simplification process easier.
