ABSTRACT:
Methods and apparatus are provided for programmable decoding of a plurality of code types. A method is provided for decoding data encoded using one of a plurality of code types, where each of the code types correspond to a communication standard. The code type associated with the data is identified and the data is allocated to a plurality of programmable parallel decoders. The programmable parallel decoders can be reconfigured to decode data encoded using each of the plurality of code types. A method is also provided for interleaving data among M parallel decoders using a communications network. An interleaver table is employed, wherein each entry in the interleaver table identifies one of the M parallel decoders as a target decoder and a target address of a communications network for interleaved data. Data is interleaved by writing the data to the target address of the communications network. The communications network can comprise, for example, a cross-bar switch and/or one or more first-in-first-out buffers.
