Systems and methods for lost synchronization data set reprocessing

摘要

Systems and method relating generally to data processing, and more particularly to systems and methods for segmenting a data set and recovering the segmented data set. In one particular example, a method is disclosed that includes: querying an input data set for an actual sync mark; forcing a proxy sync mark where the actual sync mark is not found in the input data set; applying data processing to the input data set to yield a processed output; correlating a potion of the processed output with a corresponding portion of the input data set to yield a true sync location; calculating a difference between the true sync location and the location of the forced sync mark to yield an offset; re-forcing the proxy sync mark based upon the offset; and re-applying the data processing to the input data set aligned using the re-forced proxy sync mark to yield a re-processed output.

1. A data processing system, the system comprising:
a sync mark detection and forcing circuit operable to:
query an input data set to identify an actual sync mark; andforce a proxy sync mark at a first location where the actual sync mark is not identified; andre-force the proxy sync mark based upon an offset; a data processing circuit operable to:
apply a data processing algorithm to the input data set aligned using the forced proxy sync mark to yield a processed output; andre-apply the data processing algorithm to the input data set aligned using the re-forced proxy sync mark to yield a re-processed output; and a reverse sync mark derivation circuit operable to:
correlate a portion of the processed output with a corresponding portion of the input data set to yield a true sync location; andcalculate a difference between the true sync location and the first location to yield the offset.
