| Abstract: | In this paper,the application of extraction principle for logic function minimiza- tion to multi-output case is studied.A defect in original algorithm in dealing with multi-output extrema is made up,and on this base,three kinds of less-than terms in different conditions are defined.In addition,three kinds of generalized definition of less-than terms are given,so as to find out more efficiently the covers with minimal number of terms and irredundant function outputs. This work makes the multi-output extraction principle closer to perfection.An algorithm based on the work is presented. |
