PERFORMANCE ANALYSIS OF AN ENERGY EFFICIENT FFT PROCESSOR USING 32nm CMOS TECHNOLOGY

ABSTRACT This paper presents an energy-efficient Fast Fourier Transform (FFT) processor which meets the requirements of DSP applications. Fast Fourier Transform is one of the widely used digital signals processing (DSP) algorithms which analysis the signal in its frequency domain. Modified DOMS-FF (Duration Observation Master Slave-Flip Flop) is introduced to reduce the power dissipation and makes the computation of the result much faster than the existing system. The goal of this work is to get less area and energy efficient FFT processor with build in all requirements necessary for DSP applications
