Paper Title
Design and Implementation of 64 X 64 Bit Vedic Multiplier

Abstract
Multipliers play an important role in digital signal processing (DSP) applications. It improves the speed and reduces resource consumption while designing FIR filters. Vedic mathematics provides many formulas for fast multiplications. Urdhva – tiryagbhyam is one such formula for fast multiplication. It can be used to design fast multipliers. This paper presents a new 64-bit multiplier based on this formula.The multiplier has been implemented using Xilinx ISE 14.7 software. The implementation has been carried out on four FPGA families: Kintex-7, Virtex-6, Virtex-5, and Spartan-6, and a comparative analysis has been with the existing design in the terms of area and timing delay. An improvement of 14.89% is reported using Virtex-6 FPGA. While an 8.29% reduction in resource consumption is achieved on Spartan-6 implementation compared to the existing design.
