An efficient finite state machine implementation of a string matching that relies upon a Content Addressable Memory (CAM) or a CAM-equivalent collision-free hash-based lookup architecture with zero false positives used as a method for implementing large FSMs in hardware using a collision-free hash-based look up scheme with low average case bandwidth and power requirements that overcomes prior art limitations by providing the ability to match an anchored or unanchored input stream against a large dictionary of long and arbitrary length strings at line speed. It should be noted that in the context of the described embodiments, a string could take many forms, such as a set of characters, bits, numbers or any combination thereof.
