Abstract
Systems, devices, and methods for decoding information bits obtained from storage, including obtaining a codeword from among a plurality of codewords stored in a storage device, wherein the codeword includes a plurality of frames; obtaining an initial error locator polynomial (ELP) corresponding to the codeword; decoding a frame of the plurality of frames; based on determining that the frame is successfully decoded, determine an updated ELP based on the initial ELP and information about the frame; and obtaining information bits corresponding to the codeword based on the updated ELP, wherein the updated ELP includes a plurality of updated coefficients, and wherein the updated ELP is determined by simultaneously calculating at least two updated coefficients from among the plurality of updated coefficients.
