Systems and methods for calibration coasting in a data processing system

摘要

The present inventions are related to systems and methods for data processing, and more particularly to systems and methods for coasting one or more calibration loops based upon identification of a probability of data inaccuracies. One embodiment is a data processing system that includes: a defect detector circuit operable to identify a defect region during a first pass processing of a received data set; a defect location buffer operable to maintain an indication of the defect region in the received data set; and a calibration circuit operable to adaptively update a calibration output during a second pass processing of the received data set, where updating the calibration output is disabled for one or more samples of the received data set corresponding to the indication of the defect region.

1. A data processing system, the data processing system comprising:
a defect detector circuit operable to identify a defect region during a first pass processing of a received data set; a defect location buffer operable to maintain an indication of the defect region in the received data set; a calibration circuit operable to adaptively update a calibration output during a second pass processing of the received data set, wherein updating the calibration output is disabled for one or more samples of the received data set corresponding to the indication of the defect region; and a data detector circuit operable to apply a data detection algorithm based at least in part on the calibration output to a detector input derived from the received data set during the first pass processing of the received data set to yield a detected output.
