Fast Fourier Transform, FFT, algorithms are interesting for direct hardware implementation in VLSI. The description of FFT algorithms is typically made either in terms of graphs illustrating the dependency between different data elements or in terms of mathematical expressions without any notion of how the computations are implemented in space or time. Expressions in the notation used in this paper can be given an interpretation in the implementation domain. The notation is in this paper used to derive a description of array implementations of decimation-in-frequency and decimation-in-time FFT algorithms. Correctness of the implementations is guaranteed by way of derivation.
