Design of Reversible Circuits for Code Converter and Binary Incrementer

Development of computing machines found great success in recent decades. But the on-going miniaturization of integrated circuits will be reached in the near future, its limits. Shrinking transistor sizes and power are the main obstacles in the development of smaller and more powerful circuits. Reversible logic is an alternative way that may overcome many of the existing problems in the future. Reversible logic has promising applications in the field of quantum computing, optical computing, low power computing and other emerging computing technologies. In this paper, we present a modular synthesis method to realize reversible circuits for Code Converter and Binary Incrementer. The circuits are evaluated in terms of number of ancilla bits, number of garbage bits and quantum cost. This paper provides a threshold to build more complex circuits using reversible logic.
