Many areas of research, especially astrophysics, require high-speed logic circuits to perform real time signal processing. A common algorithm used in signal processing for such purpose is the Fast Fourier Transform (FFT). It is one of the vital operations used in the field of signal and image processing. Some of the important applications of FFT include spectrum analysis, image filtering, data compression, linear filtering of signals, etc. In this work we have focused on efficient implementation of FFT IP core available in Quartus Prime software for Intel FPGAs, in terms of reduced processing time or resource usage. It is more efficient than direct use of FFT IP core but with additional logic elements. The approach shows optimization of 2048-point FFT IP core implemented for Cyclone V FPGA and various supporting modules developed with the help of Verilog language.
