Area-Delay-Power Efficient Booth Encoded Reversible Multiplier Using Compressors

Reversible logic gates became very important and promising technology having more applications in low power CMOS design, Quantum computing, Optical computing and Nano Technology. The basic set of gates like AND, OR, XOR are not reversible. A set of reversible gates has been introduced by various researchers. Few basic reversible gates are Feynman, Toffoli, TSG, Fredkin, Peres etc. Theoretically it has been proved that energy dissipation would not occur if a computation is carried out in a reversible way. This paper proposes a Novel reversible Radix 4 Booth Encoded Wallace Tree multiplier using 4:2 compressors, 5:2 compressors.
