Generating New Reversible Logic Gates with Ladder Block Structure for Emerging Nanocircuits
Bahram Dehghan · 2013
Reversible computing is an emerging scene of research and reversible logic synthesis is its significant aspect. The present study aims to generate the reversible logic gates with new outputs that never been seen. In this paper, the schematic diagram with minimum quantum cost for reversible gate and combination of several quantum gates is considered. I illustrate that we can displace control-bit and target-bit in Feynman gate and produce EXNOR gate in output. Also, N number of ladder Feynman gate can produce (N+1)EXOR gate without any garbage output. The new reversible logic gates from FG, F2G, PG, TG, BVF, R and TR gates is generated. Sometimes, the available gates are from the same kind and can extract an ideal output, though we should consider the speed and the wasting power. The resulting ladder gates realization has been depicted in the following figures. All the results verify with the truth table. This work with recently outputs introduced for the first time.
