Abstract
Systems and methods are disclosed for implementing a low latency decoder. In certain embodiments, an apparatus may comprise decoder configured decode a codeword of bits, including: a variable node processor configured to provide a plurality of variable-to-check (v2c) message vectors to the edge combiner in parallel, the plurality of v2c message vectors including estimates for a selected set of bits of the codeword; the edge combiner configured to generate a plurality of output message vectors for a plurality of check node vectors based on the plurality of v2c message vectors, and provide the plurality of output message vectors to the plurality of check node vectors simultaneously; a check node processor configured to update the plurality of check node vectors based on the plurality of output message vectors; and a convergence checker circuit configured to detect a valid code word based on bit value estimates from the variable node processor.
