Abstract: Systems and methods which provide parallel processing of multiple message bundles for a codeword undergoing a decoding process are described. Embodiments provide low-latency segmented quasi-cyclic low-density parity-check (QC-LDPC) decoder configurations in which decoding process tasks are allocated to different segments of the low-latency segmented QC-LDPC decoder for processing multiple bundles of messages in parallel. A segmented shifter of a low-latency segmented QC-LDPC decoder implementation may be configured to process multiple bundles of a plurality of edge paths in parallel. Multiple bundles of messages of a same check node cluster (CNC) are processed in parallel. Additionally, multiple bundles of messages of a plurality of CNCs are processed in parallel.

Abstract: Systems and methods which provide parallel processing of multiple message bundles for a codeword undergoing a decoding process are described. Embodiments provide low-latency segmented quasi-cyclic low-density parity-check (QC-LDDC) decoder configurations in which decoding process tasks are allocated to different segments of the low-latency segmented QC-LDPC decoder for processing multiple bundles of messages in parallel. A segmented shifter of a low-latency segmented QC-LDPC decoder implementation may be configured to process multiple bundles of a plurality of edge paths in parallel.
