A technique for decoding an encoded data stream representing an original sequence of data bits, each data bit comprising a plurality of codes, each code being dependent on a current data bit and a first predetermined number of preceding data bits in the original sequence. Scores are provided indicating the likelihood that a corresponding state represents the first predetermined number of preceding data bits. The scores are arranged in an initial ordering. A first plurality of score bit slices are stored to collectively represent the initially ordered scores, each score bit slice containing a predetermined bit from each of the scores. The scores are then reordered and a second plurality of score bit slices are stored to collectively represent the reordered scores. By this approach, all the scores are updated simultaneously.
