Abstract
A low-density parity-check (LDPC) decoder may receive LDPC coded data. The LDPC decoder may perform a decoding iteration associated with decoding the LDPC coded data. The decoding iteration may be performed by processing a group of layers. Each layer may include a corresponding set of check node elements, and may be processed by causing each check node element, of the set of check node elements corresponding to the layer, to update a set of variable node elements, connected to the check node element and associated with the LDPC coded data, based on a check node function associated with the check node element. The decoding iteration may be performed such that each layer is processed in parallel, and such that each check node element updates the corresponding set of variable node elements in parallel. The LDPC decoder may provide a result of performing the decoding iteration.
