FPGA Implementation of 8-Bit Vedic Multiplier for DIT-FFT Application Using Urdhva Tiryagbhyam Sutra

Abstract

This paper discusses FPGA Implementation of 8-Bit Vedic Multiplier and DIT-FFT Application Using Urdhva Tiryagbhyam Sutra. Initially 8-bit Vedic multiplier performance is compared with existing multiplier such as i) Wallace tree multiplier ii) Array multiplier iii) Booth multiplier. In this work Urdhva Tiryagbhyam (upright and across) Vedic sutra is used for multiplier design which provides better performance and consumes smaller time for computation. In this work, Modified Carry Save Adder (MCSA) is used to compute the sum of partially generated products. Further the multiplier is It reduces the computational delay towards the addition of unfinished products. The proposed design uses the Verilog HDL to develop the algorithm. The XILINX 14.7 software tool is used to simulate and synthesize the code. The proposed design is used for DIT FFT application.
