Abstract
Methods and apparatus are provided for programmable codeword encoding and decoding. Data blocks are represented as a number of codewords. Data is encoded into one or more full size codewords and at least one truncated codewords. Typically, data is encoded and decoded using one or more full size codewords and one truncated codeword. The truncated codewords are a two-dimensional array having a number of columns (or rows or both) less than the full size codeword. In this manner, the disclosed truncated codewords are adaptable to various system parameters that affect code rate.
