Abstract

This paper considers the synthesis of reversible circuits directly from an irreversible specification, with no need for producing a reversible embedding first. We present a feasible methodology for realizing the networks of reversible gates, in a manner that builds on the classical technology mapping. We do not restrict ourselves to the restricted notion of realizing permutation functions, and construct reversible implementations where extraneous signals are efficiently reused for overcoming the inherent fanout limitation.
