Abstract

Reversible Logic is a very promising and flourishing research area. Reversible logic theoretically allows designers to build subsystem circuit design with zero power dissipation than the existing classical ones. However synthesis of reversible circuit is not easy. In this paper we propose an efficient approach for carry skip BCD adder using reversible logic. Our results show that our design is much more efficient than the existing ones in terms quantum cost, garbage outputs and delay.
