Abstract: FFT architecture is the common and very efficient design in modern signal processing applications. Though so much of architectures are executed in now-a-days applications, This paper will give different approach of FFT design. In order to reduce the computation time, FFT structure is modified in the arrangement. This analyzed approach somewhat satisfies the low power, high performance and to useful in image, signal and wireless applications.
