摘要:
The present inventions are related to systems and methods for iterative data processing scheduling. In one case a data processing system is disclosed that includes a data detector circuit and a data decoder circuit. The data detector circuit is operable to apply a data detection algorithm to a data set to yield a detected output. The data decoder circuit is operable to repeatedly apply a data decoding algorithm to the detected output to yield a decoded output over a number of passes, where the number of passes is within an allowable number of local iterations selected based at least in part on a read gate signal.

The present inventions are related to systems and methods for information data processing included selective decoder message determination. In one example, a data processing system is disclosed that includes a data decoder circuit operable to apply a conditional data decoding algorithm to a data set to yield a decoded output. The conditional decoding algorithm is operable to calculate node messages using an approach selected from a group consisting of: a first message determination mechanism, and a second message determination mechanism; where one of the first message determination mechanism and the second message determination mechanism is selected based upon a condition that includes a global iteration count applied to the data set.

Various embodiments of the present invention provide systems and methods for media defect detection. As an example, a data processing circuit is disclosed that includes a defect detector circuit and a comparator circuit. The defect detector circuit is operable to calculate a correlation value combining at least three of a data input derived from a medium, a detector extrinsic output, a detector intrinsic output and a decoder output. The comparator circuit is operable to compare the correlation value to a threshold value and to assert a media defect indicator when the correlation value is less than the threshold value.

The present invention is related to systems and methods for enhancing data detection in a data processing system. In one embodiment, a data processing system is disclosed that includes a data detector circuit that is governed at least in part based upon selected coefficients. The selected coefficients are selected as either a first set of coefficients or a second set of coefficients where the second set of coefficients has fewer coefficients than the first set of coefficients.
