    摘要: Various embodiments of the present invention provide systems and methods for data processing. A data processing circuit is disclosed that includes: a data detector circuit, a first symbol constrained arrangement circuit, and a second symbol constrained arrangement circuit. The data detector circuit is operable to apply a data detection algorithm to a combination of a first input data set and a decoded data set to yield a detected output that includes a number of non-binary symbols. The first symbol constrained arrangement circuit is operable to receive the detected output and to re-arrange the detected output in accordance with a first arrangement algorithm to yield a re-arranged output. The bits for at least one non-binary symbol from the detected output are maintained together in the re-arranged output. The second symbol constrained arrangement circuit is operable to receive a second input data set and to re-arrange the second data input in accordance with a second arrangement algorithm to yield the decoded data set. The bits for at least one non-binary symbol from the second input data set are maintained together in the decoded data set output.

    摘要: Various embodiments of the present invention provide systems and methods for data processing. For example, a method for data processing is disclosed that includes receiving a codeword that has at least a first circulant with a plurality of data bits and a first circulant parity bit, a second circulant with a plurality of data bits and a second circulant parity bit, and one or more codeword parity bits. The methods further include decoding the codeword using the one or more codeword parity bits to access the first circulant and the second circulant, performing a first circulant parity check on the first circulant, and performing a second circulant parity check on the second circulant.

    摘要: In a hard-disc drive, a defect region on the hard disc is classified as corresponding to either thermal asperity (TA) or media defect (MD) by generating two statistical measures. A first measure (e.g., α1) is based on (i) the magnitudes of one or both of signal values (e.g., equalizer input or output signal values) and the corresponding expected values of those signal values and (ii) the signs of one or both of the signal values and the expected signal values. A second measure (e.g., α2) is based on the magnitudes of one or both of the signal values and the expected signal values, but not the signs of either the signal values or the expected signal values. The two measures are then compared to determine whether the defect region corresponds to TA or MD.

    摘要: Various embodiments of the present invention provide systems and methods for a data processing system with thermal control. For example, a data processing system with thermal control is disclosed that includes a number of data processors and a scheduler, which is operable to determine the power consumption of the data processors and to switch the data processing system from a first mode to a second mode and from the second mode to a third mode. The data processing system consumes less power in the third mode than in the first mode. The second mode prepares the data processing system to enter the third mode.
