| Abstract | Fast Fourier Transform (FFT) is widely used in the field of digital signal processing (DSP) such as filtering spectral analysis, etc, to compute discrete fourier transform. The appearance of radix-2 which had been a milestone in the design of pipelined FFT hardware architectures was later extended to radix-2.This project presents a new approach to develop parallel pipelined 16 point radix-2. Feed forward (MDC) FFT architectures along with data shuffling. Furthermore, decimation in frequency (DIF) decomposition has been used. The power and area consumption can be reduced in 4-parallel FFT architecture. As a result, the proposed radix-2 feed forward architectures not only offer an attractive solution for current applications, but also open up new research line on feed forward structures. The output samples are obtained, to a desired order to implement on XILINXSPARTAN-3E FPGA.
