Abstract
Fast Fourier Transform (FFT) processor plays key role in Orthogonal Frequency Division Multiplexing (OFDM) system. Power consumption, speed, accuracy and area are the key aspects of FFT. FFT finds vast application in the field of Digital and Signal Processing (DSP). The FFT processor can be used in the areas such as Digital Audio Broadcasting, Worldwide interoperability for Microwave access (Wi-Max), Digital Video Broadcasting-Terrestrial (DVB-T). In this article, we present an optimized high speed and throughput 64 × 64 non-pipelined and pipelined 2D FFT architecture with a radix-8 block structure. The designed structure is a parallel architecture that takes less computation time and also requires less area. The proposed design is realized using the Vitex-7 FPGA tool as a supplementary hardware.
