Efficient VLSI Architecture for Code Convertors

Reversible logic design(RLD) is gaining great importance due to its low power consumption and less dissipation of heat, especially Reversible logic gates(RLG) are employed in quantum computing, optical computing and designing low power CMOS, etc. Reversible logic design reduces the number of garbage output and reduces the complexity of the circuit. Code converters are widely used in digital systems for enhancing security, reducing the number of hardware components, minimizing the level of switching activities which reduces the power consumption and improves the speed of operation. In this paper we have simulated the design of code converters like Binary code to Gray code, Gray code to Binary code, BCD code to Excess-3 code and Excess-3 code to BCD code by using Reversible logic gates.
