Systems and methods for efficient parameter modification

摘要

The invention relates to a data processing system comprising: a data detector circuit (130); a data decoder circuit (170), a reliability monitor circuit (160) to calculate an error rate (225), and a parameter modification control circuit (250). Data detector circuit (130) applies a data detection algorithm to a first data set to yield a detected output (195). Data decoder circuit (170) applies a data decode algorithm to a second data set to yield the decoded output. The parameter modification circuit (250) selects a first value for a parameter and stores a first instance of the error rate corresponding to the first value; selects a second value for the parameter and stores a second instance of error count corresponding to the second value, and selects one of the first value and the second value based at least in part on a comparison of the error rates.
