Abstract

The aim of the present paper is to investigate the minimization of the power
consumption in combinational circuits by reducing the switching activity. A synthesis
approach based on an iterative procedure that compares the minterms consequently, eliminate
the complementary variables, then ORing all the terms in one simplified equation is
introduced . The results show that about 10% reduction in switching activity has been
obtained by using this method if it is compared with the normal optimal solution obtained
from K-map method
