摘要： Executed when a channel input (e.g., LDPC) codeword is written to a storage medium, a write-verification method (i) compares the channel input codeword to the written codeword, (ii) identifies any erroneous bits, and (iii) stores the erroneous-bit indices to a record in a table. At some later time, the written codeword is read and sent to a decoder. If the decoder fails with a near codeword, a write-error recovery process searches the table and retrieves the erroneous-bit information. The codeword bits at those indices are adjusted, and the modified codeword is submitted to further processing.

摘要： The present invention provides a data processing system that includes: a data detector circuit (130), a low density parity check data decoder circuit (170), and a processing circuit (175). Data detector circuit (130) applies a data detection algorithm to a data set to yield a detected output. The data set includes at least a first encoded sub-codeword and a composite sub-codeword (220), wherein the composite sub-codeword is obtained by a modulo 2 addition of a plurality of encoded sub-codewords (205, 210, 215). Low density parity check data decoder circuit (170) applies a data decode algorithm yielding a first decoded output and a second decoded output relating to the first encoded sub-codeword and the composite sub-codeword, respectively. Processing circuit (175) is operable to reconstitute a second encoded sub-codeword from a combination of the first and second decoded outputs and to correct an error in one of the first encoded sub-codeword and the second encoded sub-codeword based at least in part on a combination of the first decoded output, the second decoded output and the reconstituted second encoded sub-codeword.

A first multiplier circuit multiplies the decoded output by the first dynamic scaling value and provides a first scaled output. A detector circuit receives the first scaled output and provides a detected output. A second multiplier circuit multiplies the detected output by the second dynamic scaling value and provides a second scaled output.

摘要： Various embodiments of the present invention provide systems and methods for data processing. For example, some embodiments of the present invention provide noise reduced data processing circuits. Such circuits include a selector circuit, a sample set averaging circuit, and a data detection circuit. The selector circuit provides either a new sample set or an averaged sample set as a sample output based on a select control signal. The sample set averaging circuit receives the new sample set and provides the averaged sample set. The averaged sample set is based upon two or more instances of the new sample set. The data detection circuit receives the sample output, and performs a data detection algorithm on the sample output and provides the select control signal and a data output.
