Abstract

Reversible logic has extensive applications in emerging nanotechnologies, such as quantum computing, optical computing, ultra low power VLSI and quantum dot cellular automata. In the existing literature, designs of reversible sequential circuits are presented that are optimized for the number of reversible gates and the garbage outputs. The optimization of the number of reversible gates is not sufficient since each reversible gate is of different computational complexity, and thus will have a different quantum cost and delay. While the computational complexity of a reversible gate can be measured by its quantum cost, the delay of a reversible gate is another parameter that can be optimized during the design of a reversible sequential circuit. In this work, we present novel designs of reversible latches that are optimized in terms of quantum cost, delay and the garbage outputs. The optimized designs of reversible latches presented in this work are the D Latch, JK latch, T latch and SR latch.
