Abstract:
Systems and method relating generally to data processing, and more particularly to systems and methods for decoding information. Some disclosed systems include a first data decoding circuit, a second data decoding circuit, and a data output circuit. The second data decoding circuit is coupled to the first data decoding circuit and the data output circuit. The second data decoding circuit is operable to apply a finite alphabet iterative decoding algorithm to the first decoded output to yield a second decoded output.
Abstract:
A method for determining update candidates in a low-density parity-check decoding process includes dividing the quasi-cyclic columns into groups and identifying an update candidate in each group. One or more of the identified update candidates are then updated. In the first half of iterative process, the higher quality candidate is updated. In the second half of the iterative process, the lower quality candidate is updated.
Abstract:
Systems and method relating generally to data processing, and more particularly to systems and methods for encoding and decoding information. Some embodiments include one or both of a multi-algorithm data encoder circuit and/or a multi-algorithm data decoder circuit. In some cases, a first algorithm encoding is applied on a first section by section basis to a user data set yield an encoded portion; and a second algorithm encoding is applied on a second section by section basis to a data set derived from a subset of the encoded portion.
