Abstract
Various embodiments of the present inventions provide a symbol flipping LDPC decoding system. For example, a symbol flipping data processing system is disclosed that includes a low density parity check decoder operable to decode codewords and to identify unsatisfied parity checks, a symbol flipping controller operable to change values of at least one symbol in the codewords based on the unsatisfied parity checks to assist the low density parity check decoder to decode the codewords, a scheduler operable to control a decoding and symbol flipping mode in the low density parity check decoder and the symbol flipping controller, and a hard decision queue operable to store hard decisions for converged codewords from the low density parity check decoder.
