Reversible circuit synthesis using ACO and SA based Quine-McCluskey method
Mayukh Sarkar, Prasun Ghosal, Saraju P. Mohanty · 2013
With the tremendous growth in VLSI technology in recent years, the Integration density of the transistors has reached billions causing the scaling of transistors to touch the subatomic dimension in deep submicron regime where laws of classical physics can not survive. Due to inherent information loss and other factors associated with irreversible computing, reversible circuits are becoming more and more important in terms of computing for present and future days. However, due to several factors, known synthesis approaches of classical Boolean logic like Karnaugh Map and Quine-McCluskey method cannot be applied directly to synthesize a reversible logic. In this paper, we propose a stochastic procedure to synthesize a reversible circuit. This procedure is based on a modified version of classical Quine-McCluskey method and is being used under the wrapper of two intelligent stochastic search techniques, Simulated Annealing and Ant Colony Optimization. The experimental results are quite encouraging.
