1. A pattern detection system, the system comprising: a first pattern detector circuit operable to apply a first pattern detection algorithm to: a first portion of a data input to yield a first detected pattern indicator; and a second portion of the data input to yield a second pattern indicator. a second pattern detector circuit operable to apply a second pattern detection algorithm to: the first portion of the data input using an adapted threshold to yield a first pattern value and a third detected pattern indicator; the second portion of the data input using the adapted threshold to yield a second pattern value and a fourth detected pattern indicator; a memory circuit operable to: store the first pattern value when at least one of the first detected pattern indicator or the third detected pattern indicator indicates a found pattern; and store the second pattern value when at least one of the second detected pattern indicator or the fourth detected pattern indicator indicates a found pattern.
