An architecture for radix-2, decimation in frequency fast Fourier transform butterfly computation unit is proposed. It operates on 16 bit inputs and uses 'merged core' type of multipliers which reduce hardware components and hence promise smaller chip area. This reduction in area is achieved with negligible increase in computation delay.
