ABSTRACT

Reversible logic is an important area to carry the computation into the world of quantum computing. In this paper a 4-bit multiplier using a new reversible logic gate called BVPPG gate is presented. BVPPG gate is a 5 x 5 reversible gate which is designed to generate partial products required to perform multiplication and also duplication of operand bits is obtained. This reduces the total cost of the circuit. Toffoli gate is the universal and also most flexible reversible logic gate. So we have used the Toffoli gates to construct the designed multiplier.
