DIAGONAL ANTI-DIAGONAL MEMORY STRUCTURE

摘要

A quarter product code codeword includes various R code symbols and C code symbols each including a plurality of symbols. Each symbol is loaded into a diagonal anti-diagonal structure in two unique locations. To provide for fast loading, the symbols may be shifted by one or more shift registers associated with the diagonal or anti-diagonal structure. The two locations at which each symbol is positioned are included within different diagonals or anti-diagonals making it possible to load or unload either symbol or multiple symbols in a single clock cycle. Further, by partitioning the diagonal anti-diagonal structure, multiple respective symbols or plurality of symbols may be loaded or unloaded in a single clock cycle.

1. A diagonal anti-diagonal storage structure system comprising:
a diagonal storage subarray and an anti-diagonal storage subarray each comprising:
a plurality of storage locations arranged in a plurality of vertical stacks, and;a plurality of mirrored storage locations that are reflections of the storage locations against a central subarray bisector; an input shift register that loads a plurality of symbols of a first code symbol portion within a plurality of storage locations and that shifts and loads the plurality of symbols within a plurality of mirrored storage locations.
