    Abstract: Systems, circuits, devices and/or methods related to systems and methods for data processing, and more particularly to systems and methods for quality based scheduling processing of data sets. In some cases, a priority indication associated with a data set is modified based upon one or more factors. As an example, the priority indication may be modified based upon a number of times that a given data set processed through both a data detector circuit and a data decoder circuit.

    Abstract: Methods are provided for pattern-dependent log likelihood ratio (LLR) manipulation of a hard disk drive detector output. Generally, by observing a pattern dependency of LLRs, various rules for LLR manipulation at the detector output are outlined. The rules may provide more reliable LLR values, such as by improving signal-to-noise ratio (SNR) of the hard disk drive detector output.

    Abstract: 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.
