Abstract
High-speed multi-block-row layered decoding for low density parity check (LDPC) codes is disclosed. In a particular embodiment, a method, in a device that includes a decoder configured to perform an iterative decoding operation, includes processing, at the decoder, first and second block rows of a layer of a parity check matrix simultaneously to generate a first output and a second output. The method includes performing processing of the first output and the second output to generate a first result of a first computation and a second result of a second computation. A length of a 'critical path' of the decoder is reduced as compared to a critical path length in which a common feedback message is computed.
