Abstract
Methods and circuits process a data block of first bits. A circuit includes a register and a parallel combiner. The register is configured to store second bits. The second bits are iteratively a partial parity for each of multiple frames of the data block. The parallel combiner is coupled to the register and configured to generate a combination of bits from third bits and the second bits from the register. These third bits are iteratively those of the first bits within each of the frames of the data block. The circuit also includes respective exclusive-or circuits associated with the second bits. These exclusive-or circuits are coupled to the parallel combiner and the register. The respective exclusive-or circuit for each second bit is configured to generate the second bit from the combination of bits.
