The objectives of the project is to come up with the FPGA based Radix-4 FFT processor using CORDIC. As FFT take values in time domain and generates equivalent sample values in frequency domain, values of samples are taken as an input to the design, which is in time domain and using Decimation in Time (DIT) method for FFT computation, output is generated in terms of frequency samples. Due to in-place computation memory requirements have to reduce and using CORDIC for complex twiddle factor generation and multipli- cation the speed of the computation gets improved with less complexity. So, such kind of processor design using Radix-4 FFT instead of using Radix-2 FFT is main objective of this proposed work.
