摘要: 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.

摘要: 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.
