This paper describes two logic minimization algorithms. CAMP (Computer Aided Minimization Procedure) minimizes single functions. The minterms are covered either by essential prime implicants or by selective prime implicants. The two types of prime implicants are determined one at a time thus completely avoiding the computationally expensive covering problem. The adjacency of a minterm, that depends upon the proximity of this minterm with respect to other minterms on the Karnaugh map, guides the determination of prime implicants. This procedure is nonheuristic and has proved to be very efficient for large number of input variables. The multiple output minimization (MOM) algorithm generates the product terms with maximum sharing between the output functions. In addition to using adjacency, this procedure is also guided by the frequency with which a minterm is used by the functions. Examples show the performance of this algorithm to be equal or better than many other minimization procedures.
本文介绍了两种逻辑最小化算法。 CAMP(计算机辅助最小化过程)可最小化单个功能。最小术语由基本素数或选择性素数包含。一次确定两种素数蕴含量,从而完全避免了计算量大的覆盖问题。最小项的相邻性(取决于该最小项相对于卡诺图上其他最小项的接近程度)指导确定主蕴含项。此过程是非启发式的,已证明对于大量输入变量非常有效。多输出最小化(MOM)算法生成乘积项,并在输出函数之间实现最大程度的共享。除了使用邻接之外,此过程还受函数使用最小项的频率的指导。实例表明,该算法的性能与许多其他最小化程序相同或更好。 P>
