Abstract:
Apparatuses, systems, methods, and computer program products are disclosed for error correcting code (ECC) decoding. A score module is configured to assign a score to a variable node of low density parity check (LDPC) code decoder. The LDPC code decoder may include a plurality of variable nodes associated with a plurality of check nodes. The plurality of variable nodes may correspond to bits of a received code word. The score for the variable node may be based on a count of unsatisfied check nodes associated with the variable node. A variable node update module is configured to update the variable node based on the score. A check node update module is configured to update one or more of the check nodes based on the updated variable node.
