VLSI ARCHITECTURE OF AN 8-BIT MULTIPLIER USING VEDIC MATHEMATICS IN 180NM TECHNOLOGY

A Multiplier is one of the key hardware blocks in most fast processing system which requires less power dissipation. A conventional multiplier consumes more power. This paper presents a low power 8 bit Vedic Multiplier (VM) based on Vertically & Crosswise method of Vedic mathematics, a general multiplication formulae equally applicable to all cases of multiplication. It is based on generating all partial products and their sum in one step. The implementation is done using cadence Virtuoso tool. The power dissipation of 8x8 bit Vedic multiplier obtained after synthesis is compared with conventional multipliers such as Wallace tree and array multipliers and found that the proposed Vedic multiplier circuit seems to have better performance in terms of power dissipation.
