Power dissipation is considered as one of the most important factors while designing a circuit. Reversible logic has become a promising technology in low power design. It is because reversible logic utilizes only very less power, thereby leading to less power dissipation. Conventional circuits which are irreversible in nature are subject to very large amount of minimum power dissipation per signal transition. Reversible logic is considered as a computing paradigm in which there is a one-to-one mapping between the input and the output vectors.
