Design and implementation of efficient reversible even parity checker and generator

Communication in today's world is made efficient by digital data transmission. The digital communication employs parity generator at the source and parity checker at destination to ensure an error free transmission. This paper proposes the design of a 3-bit reversible even parity checker and generator using the basic reversible gates. The parity checker and generator circuit is designed using the existing basic reversible gates like Feynman gate, Toffoli gate, Peres gate and New gate and the performance of the designed parity checker and generator is discussed. The proposed design is designed using Modelsim and synthesized using Xilinx Virtex5vlx30tff665-3.
