摘要

A method and apparatus are provided for implementing data mapping using a shuffle algorithm. An output shuffler and an input shuffler convert a physical data group to a plurality of data subgroups. The physical data group includes a plurality of bits and each subgroup includes a subplurality of bits. The output shuffler performs an output shuffle sequence for providing a predefined output pattern of ordered subplurality data bits. The predefined output pattern of ordered subplurality data bits is applied to the input shuffler. The input shuffler performs a reverse shuffle sequence. For each shuffle transfer a number of first header bytes of a packet are located at a first one of a plurality of physical layer links. Both the output shuffler and the input shuffler are implemented with minimized logic required to keep a largest multiplexer as a 4-to-1 multiplexer, resulting in minimal area and power being used for implementing the shuffle sequence and reverse shuffle sequence.
