“…It leaves aside the consumption of memory space and time while calculating the complement set. On the basis of analyzing and mastering the algorithm of Espresso, Vanilla, Beister, etc[9-10], a software system of multi-input multi-output logic functions optimization algorithm based on minterm is designed [11]. For two-level SOP multi-input & multi-output logic function, max-input variables is 128,maxoutput variables is 256,sum of max-input-output variables is 300, max-input products is 20000 according to the hardware of computer in fact.…”
