| Abstract(in English) | This paper presents a design method for AND-OR-EXOR three-level networks, where a single two-input EXOR gate is used. The network realizes an Exclusive-OR of two sum-of-products expressions (EX-SOP). The problem is to minimize the total number of product terms. Algorithms for minimization of EX-SOPs with up to five variables are shown. A heuristic algorithm is also presented to simplify EX-SOPs with six or more variables. Up to five variables, all the representative functions of NP-equivalence Classes were minimized. For five-variable functions, the upper bound on the number of products in minimum EX-SOPs is found to be 9. For n-variable (n ≥ 6) functions, minimum EX-SOPs require at most 9.2^ |
