1. A data processing system, the system comprising:
a first pattern identification circuit operable to identify a first pattern in a first subset of a data set; a second pattern identification circuit operable to identify a second pattern in a second subset of the data set, wherein all of the elements of the second subset are excluded from the first subset; a distance calculation circuit operable to calculate a distance between the first pattern and the second pattern; and a quality output circuit operable to provide a quality metric corresponding to the distance between the first pattern and the second pattern.
