Systems and methods for parameter selection using reliability information

摘要

Various embodiments of the present invention provide systems and methods for data processing. For example, a data processing system is disclosed that includes: a data detector circuit, and a reliability monitor circuit. The data detector circuit is operable to apply a data detection algorithm to a data set to yield a detected output that includes soft data. The reliability monitor circuit is operable to determine a proxy error count based at least in part on the soft data, and to modify a parameter governing an operation of the data processing system based at least in part on the proxy error count.
