Efficient Algorithm for Positive-polarity Reed-muller Expansions of reversible circuits

Abstract

In this paper, we build mathematical modeling for reversible circuits and derive required parameters of cost function from this modeling. The heuristic algorithm plots out reversible circuit into some partitions, uses a priority queue based on search tree and explores candidate components at each partition in order of utilization ratio. We demonstrate that using this heuristic, path delay can be reduced by 8% compared to existing synthesis method. The improvements increase for strict delay constraints making synthesis especially important for high performance and a large number of inputs and outputs designs.
