Efficient Building Blocks for Reversible Sequential Circuit Design

Abstract

Reversible logic is gaining interest in the recent past due to its less heat dissipating characteristics. It has been proved that any Boolean function can be implemented using reversible gates. In this paper we propose a set of basic sequential elements that could be used for building large reversible sequential circuits leading to logic and garbage reduction by a factor of 2 to 6 when compared to existing reversible designs reported in the literature.
