Permutation blocks in folded hardware FFTs can be implemented in one of two ways: either usingdedicated permutation logic or using address generation schemes. Although the abstract Cooley–Tukey factorization of the DFT, above, applies in some form to all implementations of the algorithm, much greater diversity exists in the techniques for ordering and accessing the data at each stage of the FFT. Of special interest is the problem of devising an in-place algorithm that overwrites its input with its output data using only O(1) auxiliary storage. The most well-known reordering technique involves explicit bit reversal for in-place radix-2 algori…
