Design of hardware RGB to HMMD converter based on reversible logic

摘要

Reversible logic computation is one of the most essential promising technologies in designing low-power digital circuits, optical information processing, quantum dot cellular automata, fault tolerant system and nanotechnology. In fact, the conventional digital circuits dissipate a significant amount of energy because several bits of information are deleted during the treatments. In reversible computation, the information bits are not lost. This study presents a novel design of reversible RGB to HMMD converter circuit. The proposed hardware converter is based on several reversible sub-modules as: adder, subtractor, multiplier, register, multiplexer comparator and others. In order to demonstrate the efficiency of the proposed logic design, each sub-module is shown in terms of number of quantum cost needed, gates required delay and garbage outputs produced. Since the works in the field of reversible logic video treatment has only started to bloom, the proposed contribution will engender a new thread of research in the field of reversible real time video treatment.
