Abstract
A method includes, in an Error Correction Code (ECC) decoder that includes variable nodes and check nodes, receiving in a given variable node Check-to-Variable (C2V) messages from a subset of the check nodes. Magnitudes for respective Variable-to-Check (V2C) messages to be sent to the check nodes in the subset are computed based on the received C2V messages. A single sign is computed, for use in all the V2C messages to be sent from the given variable node to the check nodes in the subset. The V2C messages are sent from the given variable node to the check nodes in the subset, such that each V2C message includes a respective magnitude and the single sign.
