—Reversible logic is one of the basis of future
computing system that promises zero energy dissipation. It has
applications in various fields such as Low power VLSI, Fault
tolerant designs, quantum computing, nanotechnology, DNA computing, optical computing, cryptography and informatics. To make reversible logic circuits reliable, they must incorporate fault tolerance attribute. In this paper, we
propose a new parity preserving reversible logic gate. We have
proposed two optimized design of a self checking two rail
checker circuit based on proposed parity preserving reversible
logic gate in terms of number of gates and critical path delay.
The proposed design achieves less critical delay and gates
compared to the existing designs available in literature.
—Critical delay, fault tolerant, paritypreserving
reversible gates, two rail checker.
