    摘要: 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.

    摘要: A built in self test circuit in a memory matrix. Memory cells within the matrix are disposed into columns. The circuit has only one memory test controller, adapted to initiate commands and receive results. Transport controllers are paired with the columns of memory cells. The controllers receive commands from the memory test controller, test memory cells within the column, receive test results, and provide the results to the memory test controller. The transport controllers operate in three modes. A production testing mode tests the memory cells in different columns, accumulating the results for a given column with the controller associated with the column. A production testing mode retrieves the results from the controllers. A diagnostic testing mode tests memory cells within one column, while retrieving results for the column.
