Abstract

This paper focus on the study of an efficient Radix-4 FFT and CORDIC algorithm. Due to use of Radix-4 speed gets doubled than Radix-2 in FFT computation. For twiddle factor calculation Co-ordinate Rotation Digital Computer (CORDIC) algorithm is used, which will reduce the computation time and make processor faster. The CORDIC offers the opportunity to calculate all the required functions in a rather simple and elegant fashion. In the next phase of this paper, actual Implementation of FFT processor on FPGA will be done using VHDL.
