Abstract
The various implementations described herein include systems, methods and/or devices for enhancing the performance of error control decoding. The method includes receiving at an LDPC decoder data from a storage medium corresponding to N variable nodes. The method further includes: updating a subset of the N variable nodes; updating all check nodes logically coupled to the updated subset of the N variable nodes; and generating check node output data for each updated check node including at least an updated syndrome check. Finally, the method includes: stopping decoding of the read data in accordance with a determination that the syndrome checks for all the M check nodes are valid syndrome checks or initiating performance of the set of operations with respect to a next subset of the N variable nodes in accordance with a determination that the syndrome checks for all the M check nodes include one invalid syndrome check.
