    摘要： Cyclic redundancy check (CRC) processing is applied to a received sequence of data blocks that are defined by respective sequences of sets of parallel data. For each data block, there is produced a sequence of syndromes that respectively correspond to the sets of parallel data within the data block. The final syndrome in the sequence of syndromes corresponds to all of the data in the data block. The time required for CRC processing can be reduced by concurrently producing first and second ones of the syndromes that respectively correspond to first and second ones of the sets that are respectively contained in first and second ones of the data blocks.

    摘要： An initial syndrome for use by a next-state decoder in a cyclic redundancy check apparatus can be inserted independently of the syndrome feedback path and its associated clock. This eliminates a clock cycle penalty that would otherwise be imposed on an incoming data stream each time the initial syndrome value is inserted.

    摘要： Cyclic redundancy check processing is applied advantageously to a set of input data that includes an unknown data portion and a data portion that is already known before the unknown data portion becomes available. A syndrome contribution that the already-known data portion contributes to a syndrome for the set of input data is determined before the unknown data portion becomes available. When the unknown data portion becomes available, the syndrome for the set of input data is determined based on the unknown data portion and the syndrome contribution.

    摘要： A sequence of cyclic redundancy check syndromes can be produced based on a received sequence of sets of parallel data wherein different ones of the sets can have respectively different parallel data widths. Some of the syndromes are produced based on respectively corresponding ones of the sets that each have a first parallel data width. At least one of the syndromes is produced based on a corresponding at least one of the sets that has a second parallel data width that is less than the first parallel data width. The last syndrome of the sequence of syndromes corresponds to all of the data in the received sequence of sets.
