A network for the evaluation of the fast Fourier transform (FFT) is presented. Such a network is able to compute, in parallel, the FFT's of arbitrary partitions in powers of two of the N input elements. It is shown that, under a VLSI model of computations, such a design requires the same asymptotical area and attains the same throughput as the corresponding network for the evaluation of a single N-element FFT.
