ABSTRACT:
A variable length string matcher finds the longest string in a stored sequence of data elements (e.g., in a history buffer) that matches a string in a given sequence of data elements. The matcher includes circuitry that operates iteratively to compare data elements of the strings and determine the longest matching string based on when an iteration does not result in issuance of a match signal. In another aspect, the history buffer is an associative content addressable memory (CAM), and the string matcher uses absolute addressing of the CAM to determine the longest matching string.
