Abstract
There is provided a method of sequential list decoding of an error correction code (ECC) utilizing a decoder comprising a plurality of processors. The method comprises: a) obtaining an ordered sequence of constituent codes usable for the sequential decoding of the ECC; b) executing, by a first processor, a task of decoding a first constituent code, the executing comprising: a. generating decoding candidate words (DCWs) usable to be selected for decoding a subsequent constituent code, each DCW associated with a ranking; b. for the first constituent code, upon occurrence of a sufficiency criterion, and prior to completion of the generating all DCWs and rankings, selecting, in accordance with a selection criterion, at least one DCW; c) executing, by a second processor, a task of decoding a subsequent constituent code, the executing comprising processing data derived from the selected DCWs to generate data usable for decoding a next subsequent constituent code.
