A power efficient Fast Fourier Transform (FFT) processor for use in the Direction Of Arrival (DOA) estimation of a wideband waveform is presented. The target device for implementation is a Xilinx Spartan-3 Xc3s200 Field Programmable Gate Array (FPGA). The FFT processor was developed using the Xilinx ISE in verilog code. Although the parallel and pipelined architecture uses a large portion of the available FPGA resources, the architecture does yield a high throughput. The total power consumed by the design is 0.081W.
