Minimization of Reversible Adder Circuits

Saiful Islam and Rafiqul Islam

Abstract

Losing information causes losing power. Information is lost when the input vector cannot be uniquely recovered from the output vector of a combinational circuit. The input vector of reversible circuit can be uniquely recovered from the output vector. In this study we have emphasized on the design of reversible adder circuits that is efficient in terms of gate count, garbage outputs and quantum cost and that can be technologically mapped. It has been analyzed and demonstrated that the results of our proposed adder circuits shows better performance compared to similar type of existing designs. Technology independent equations required to evaluate these circuits have also been given.
