Abstract

A low-density parity-check (LDPC) codeword is decoded by performing a partial parity check, and based on the partial parity check, determining whether an iteration condition is met. Determining whether the iteration condition is met includes determining whether a time to decode a last codeword is approaching. Determining whether the iteration condition is met can additionally include determining whether a number of partial iterations reaches a maximum number of iterations and/or determining whether hardware resources are becoming limited. If the iteration condition is met, a decoding result is reported. If the iteration condition is not met, then a plurality of check nodes are updated and a parity check is performed.
