    摘要： Systems and methods for resource allocation for a large sector format processing may include, but are not limited to, operations for: determining non-convergence of a magnetic disc sub-sector of a first magnetic disc sector within a processing time frame allocated to the magnetic disc sub-sector; determining a convergence of a second magnetic disc sector occurring in less time than a processing time frame allocated to the second magnetic disc sector; and processing the magnetic disc sub-sector during a portion of the processing time frame allocated to the second magnetic disc sector remaining after processing of the second magnetic disc sector.

    摘要： Methods are systems for calculating log-likelihood ratios for a decoder utilized in an electronic non-volatile computer storage apparatus are disclosed. A log-likelihood ratio handler is configured to provide an input log-likelihood ratio to the decoder, wherein the input log-likelihood ratio is one of: a uniform input log-likelihood ratio for all bits calculated based on an estimated raw bit error rate for a particular data unit, or a bit-based input log-likelihood ratio for each bit calculated based on a confidence value for a cell containing said each bit. The decoder of the electronic non-volatile computer storage apparatus is configured to decode encoded data at least partially based on the input log-likelihood ratio from the log-likelihood ratio handler.

    摘要： The present inventions are related to systems and methods for data processing, and more particularly to systems and methods for performing data decoding. In one case a data processing system is disclosed that includes a decoder circuit operable to apply a low density parity check algorithm to a decoder input to yield an interim decoded output, where the decoder input is a codeword formed of two bit symbols, and where the decoder input is encoded to yield a last layer including at least two different entry values. In addition, the data processing system includes an inverse mapping circuit operable to remap the interim decoded output to yield an overall decoded output.

    摘要： Systems and methods for data processing particularly related local iteration randomization in a data decoding circuit. In some cases a data processing system may include: a layered data decoding circuit, a value generator circuit, and a selector circuit. The layered data decoding circuit is configured to iteratively apply a data decoding algorithm up to a selected number of times to a decoder input to yield a decoded output in accordance with a layer order. The value generator circuit is operable configured to generate an adjusted number of times where the adjusted number of times is less than a default number of times. The selector circuit is operable configured to select one of the default number of times and the adjusted number of times as the selected number of times.
