摘要：
In one embodiment, a method of block decoding is provided. For each of a plurality of data blocks input to a memory arrangement, a plurality of decoding iterations are performed using a circular pipeline of processing stages. For each decoding iteration, one processing stage of the circular pipeline performs a first set and a second set of soft-input-soft-output (SISO) decoding operations on a block of data. The first set of SISO decoding operations produces an intermediate block of data. The second set of SISO decoding operations is performed on the intermediate data block to complete the one decoding iteration. The next decoding iteration of the plurality of decoding iterations is performed using the next processing stage following the one processing stage of the circular pipeline of processing stages.
