This paper will study a novel system on chip (SoC) design for fast Fourier transform (FFT) module. We first explain the role and position of FFT module in a digital intelligent system. Then, the discrete Fourier transform (DFT) and decimation in frequency (DIF) Radix-2 butterfly FFT algorithm is explained in detail, mathematically. In addition, the analysis of a simple pipeline FFT processor and a single-path delay feedback pipeline FFT processor based on SDF Radix-2 algorithm are discussed. Finally, the implementation and verification of proposed FFT processor are performed VERILOG hardware description language (HDL).
