    Abstract: Systems and methods for data processing. In one case, a data processing system includes a data detector circuit configured to apply a data detection algorithm to a detector input to yield a second detected output, and a data decoder circuit configured to apply a data decoding algorithm to a decoder input to yield a decoded output. The decoder input is derived from an interim data set calculated as a combination of at least a first detected output and the second detected output.

    Abstract: Systems, circuits, devices and/or methods related to systems and methods for data processing, and more particularly to systems and methods for priority based data processing. As one example, a data processing system is disclosed that includes a data detector circuit, a data decoder circuit, a memory circuit, and a scheduling circuit. The scheduling circuit is operable to select one of a first data set and the second data set as a detector input for processing by the data detector circuit.

    Abstract: Systems and methods for computing sign disagreement between signals may implement one or more operations including, but not limited to: receiving an extrinsic log likelihood ratio (LLR) value; incrementing a sign-disagreement counter according to a sign disagreement between the extrinsic LLR value and an a priori LLR value; providing a value of the sign-disagreement counter to a binary short media defect (SMD) detector; and detecting one or more consecutive sign disagreements between an extrinsic output of a detector and an extrinsic output of a decoder.
