Memory arbitration technique for turbo decoding

摘要

A technique for resolving access contention in a parallel turbo decoder is described. The technique includes associating a plurality of buffer memories with the subdecoders so that accesses to banks of a shared interleaver memory can be rescheduled. Accesses can be rescheduled to prevent simultaneous accesses to a single bank of the shared interleaver memory based on an interleaver pattern.
