Abstract
A data interleaving circuit and method for interleaving a data block comprising M windows of W values include an index generator for generating an intra-window index w and an inter-window permutation vectorhaving M elements and an inter-window permutation circuit operable to receive M data values having intra-window index w from a memory and further operable to reorder the M data values in accordance with the inter-window permutation vectorand output the reordered data values. The index generator includes a recursion circuit that generates the intra-window index w and inter-window permutation vectorin accordance with a permutation polynomial. In one application, the reordered data values are passed to M parallel processors of a turbo decoder.
