    摘要: Various embodiments of the present invention provide systems and methods for data processing. As an example, a data processing circuit is disclosed that includes: a data detector circuit, a data decoder circuit, and a power usage control circuit. The data detector circuit is operable to apply a data detection algorithm to a data input to yield a detected output. The data decoder circuit is operable to apply a data decode algorithm to a data set derived from the detected output to yield a decoded output. The power usage control circuit is operable to force a defined number of global iterations applied to the data input by the data detector circuit and the data decoder circuit regardless of convergence of the data decode algorithm.

    摘要: An error correction data processing apparatus includes a noise predictive calibration circuit operable to calibrate a first set of filter coefficients based on a first data set and a second set of filter coefficients based on a second data set, and includes a first noise predictive detector operable to receive the first set of filter coefficients. The apparatus further includes a decoder operable to perform a first global iteration with the first noise predictive detector and determine a violation check count value, and a second noise predictive detector operable to receive the second set of filter coefficients if the violation check count value is less than a predetermined value or receive the first set of filter coefficients if the violation check count value is greater than the predetermined value.
