ABSTRACT:
A dense modular system for the high speed computation of a composite fast Fourier transform (FFT) is disclosed. The composite FFT is formed by aggregating a series of individual FFT passes. The FFT passes are calculated within module boundaries in a substantially parallel manner and the input and output between the modules is transmitted in a substantially serial manner. The serial transmission takes place at a higher speed than the parallel FFT computation in order to preserve the constant data flow in the composite FFT.
