In this paper, a novel architecture of ASIP for a reconfigurable FFT is proposed. The proposed design implements a reconfigurable 64 points FFT processor for unsigned real numbers. By changing the value of integer constant the authors can design 2, 4, 8, 16, 32 and 64 point FFT which incorporates a high speed ASIP. In OFDMA system there is a need of alterable point FFT processor. Hence, the design meets the requirement of OFDMA system. DIF-FFT algorithm is implemented using VHDL language and Xilinx 9.1i is used for simulation results.
