[ixp1200] HELP!!

Hi There, Can anyone provide me with code to do the following.. I want to create a lookup table in SRAM as follows: ------------------------------------------- | packet offset | signature len | signature | N matched pkts| ------------------------------------------- | | | | ------------------------------------------- As packets arrive I want to search this table and increment the N matched packets counter if a packet contains any of the signatures in the table. Any help will be greatly appreciated, Thanks for your time, Denis
