Methods and systems for content detection in a reconfigurable hardware

A system for identifying a repeating content in a data stream, the system comprising:

• a hash function computation circuit that computes a hash function for the least one portion of the plurality of portions of the data stream;
• a plurality of counters, at least one counter of a plurality of counters being incremented responsive to the computed hash function result, each counter corresponding to a respective computed hash function result;
• a repeating content identifier that identifies the repeating content when the at least one of the plurality of counters exceeds a count value;
• and
• a verifier that verifies that the identified repeating content is not a benign string.

A system for identifying a repeating content in a data stream, the system comprising:

• means for computing a hash function for at least one portion of a plurality of portions of the data stream, the at least one portion of the data stream having benign characters removed therefrom to prevent the identification of a benign string as the repeating content;
• means for incrementing at least one counter of a plurality of counters responsive to the computed hash function result, each counter corresponding to a respective computed hash function result;
• means for identifying the repeating content when the at least one of the plurality of counters exceeds a count value;
• and
• means for verifying that the identified repeating content is not a benign string.
