    摘要: Systems and method relating generally to data processing, and more particularly to systems and methods for combining recovered portions of a data set. In one particular case, a system is disclosed that includes a stitching circuit and a data recovery circuit. The stitching circuit is operable to: receive a data set including at least a first fragment and a second fragment; replicate data from at least one of the first fragment and the second fragment as stitching values; and aggregate the first fragment with the second fragment with the stitching values between the first fragment and the second fragment to yield a combined data set. The data recovery circuit is operable to process the combined data set to yield an original data set.

    摘要: An apparatus for low density parity check decoding includes a variable node processor and a check node processor. The variable node processor is operable to generate variable node to check node messages and to update variable node values based on check node to variable node messages. The check node processor is operable to generate the check node to variable node messages based on the variable node to check node messages. The variable node processor and the check node processor comprise a quasi-cyclic decoder with relative indexes that refer to non-zero circulants.

    摘要: A data processing system is disclosed including a low density parity check decoder with a variable node processor, a check node processor and a scaler circuit. The low density parity check decoder is operable to scale soft information with a scaling factor in the scaler circuit while iteratively generating and processing check node to variable node messages in the variable node processor and variable node to check node messages in the check node processor between a plurality of check nodes and variable nodes. The scaling factor is derived from a distribution of possible values in an input to the low density parity check decoder.

    摘要: The present inventions are related to systems and methods for data processing, and more particularly to systems and methods for use of a detector output by a data decoder. As an example, a data processing system is discussed that includes a data detector circuit operable to provide a first detector output and a second detector output, and a combining circuit operable to combine a first input derived from the first detector output with a second input derived from the second detector output to yield a combined detector output. The combined detector output includes a unified data set element generated by combining an element of the first input with a corresponding element of the second input.
