Reversible logic gates and its performances

Abstract

Heat is an important issue in VLSI circuits. But the reversible logic gives zero amount of heat dissipation. So, its an important role in nanotechnology, less energy complementary metal oxide semiconductor [CMOS] designs etc. It has been realized that quantum computing is one of the latest technologies using reversible logic gates. It is contemplating that accumulation extension of transistor density, energy desolation will command their limits in ordinary technologies. In ordinary area or range during the logic influence bits of orientation is erased resulting gratification of power in powerful amount. In the terms of reversible logic results are not lost.[1] This minimize the delays but at the amount of little hardware. So we can use reversible logic technology for decreasing the energy dispersion, heatwave dissipation, increasing rapidness etc. So it is used to maximize the speed and reducing energy consumption. In this, we can describe following reversible logic gates like fredkin, peres, Feynmen and toffoli gate etc.
