Abstract
Systems, circuits, devices and/or methods related to systems and methods for data processing, and more particularly to systems and methods for re-processing data sets not successfully processed during standard processing.
Claims20
A data processing system, the data processing system comprising:
- a data processing circuit operable to apply a data processing algorithm to a processing input to yield a data output;
- an input buffer operable to maintain at least a first data set and a second data set, wherein the first data set completed a first defined amount of processing by the data processing circuit without converging, and wherein the second data set is yet to complete a second defined amount of processing by the data processing circuit;
- a kick out circuit operable to compare an attribute of the second data set to a corresponding attribute of the first data set to determine whether the second data set will be maintained in the input buffer for additional processing after the second defined amount of processing by the data processing circuit;
- and
- wherein each of the first data set and the second data set are selectable as the processing input.

A method for data processing, the method comprising:
- providing a data processing circuit operable to apply a data processing algorithm to a processing input to yield a data output;
- providing an input buffer operable to maintain at least a first data set and a second data set, wherein the first data set completed a first defined amount of processing by the data processing circuit without converging, and wherein the second data set is yet to complete a second defined amount of processing by the data processing circuit;
- comparing an attribute of the second data set to a corresponding attribute of the first data set to determine whether the second data set will be maintained in the input buffer for additional processing after the second defined amount of processing by the data processing circuit;
- and
- selecting each of the first data set and the second data set as the processing input at respective times.

A storage device, the storage device comprising:
- a storage medium;
- a head assembly disposed in relation to the storage medium and operable to provide a sensed signal corresponding to information on the storage medium;
- a read channel circuit including:
- an analog to digital converter circuit operable to sample an analog signal derived from the sensed signal to yield a series of digital samples;
- an equalizer circuit operable to equalize the digital samples to yield a first data set and a second data set;
- a data processing circuit operable to apply a data processing algorithm to a processing input to yield a data output;
- an input buffer operable to maintain at least a first data set and a second data set, wherein the first data set completed a first defined amount of processing by the data processing circuit without converging, and wherein the second data set is yet to complete a second defined amount of processing by the data processing circuit;
- a kick out circuit operable to compare an attribute of the second data set to a corresponding attribute of the first data set to determine whether the second data set will be maintained in the input buffer for additional processing after the second defined amount of processing by the data processing circuit;
- and
- wherein each of the first data set and the second data set are selectable as the processing input.
