Applications of vedic multiplier designs - A review

Rapidly growing technology has raised demands for fast and efficient real time digital signal processing applications. Multiplication is one of the primary arithmetic operations every application demands. A large number of multiplier designs have been developed to enhance their speed. Active research over decades has lead to the emergence of Vedic Multipliers as one of the fastest and low power multiplier over traditional array and booth multipliers. Vedic Multiplier deals with a total of sixteen sutras or algorithms for predominantly logical operations. A large number of them have been proposed using Urdhava Tiryakbhyam sutra rendering them most efficient in terms of speed. The objective of this paper is to encapsulate an array of applications of Vedic Multiplier in the vast domain of Image processing and Digital signal processing, particularly the different modifications of existing Vedic Multiplier architectures enhancing their speed and performance parameters.
