Abstract: A hardware system for signature matching in a distributed network is disclosed. The hardware system comprises a network processor and a memory. The network processor is configured to perform horizontal compression on a state table using bitmaps, wherein the state table has a plurality of states and state transitions. The processor is also configured to perform a first grouping of states of the state table using the bitmaps to generate a first one or more sets of states, perform a second grouping of states of the state table based on the first one or more sets of states and a transition threshold to generate a second one or more sets of states, perform a conquer step grouping of the states of the state table based on the second one or more sets of states and conquer criteria to generate third one or more sets of states, and generate a two dimensioned compressed state table based on the third one or more sets of states. The memory circuit is configured to store the two dimensioned compressed state table.
