Systems, methods and devices for multi-tiered error correction
Abstract:
An error control encoding system produces a codeword from a data word, where the resulting codeword includes the data word and three or more parity segments produced using the data word. The system includes a first encoder to encode the data word in two or more first data segments in order to produce two or more first parity segments, where each of the two or more first data segments includes a respective sequential portion of the data word. The system includes a second encoder to encode the data word in one or more second data segments in order to produce a corresponding one or more second parity segments, where each of the one or more second data segments includes a respective sequential portion of the data word, and each of the one or more second data segments also includes a sequential portion of the data included in a plurality of the two or more first data segments. Further, the system includes a controller configured to provide the two or more first data segments of the data word to the first encoder for encoding and to provide the one or more second data segments of the data word to the second encoder for encoding.
