Abstract
Described are input output (IO) device configured to perform operations for performing a table lookup with a single wide key larger than a width of a system bus. These operations comprise: receiving the lookup key; performing a plurality of extraction cycles to determine a plurality of key fragments; calculating a final hash value for the lookup key by sequentially calculating, via a hash chain, an interim hash value for each of the key fragments; determine a read access address for a table entry of a logic table based on the final hash value for the lookup key; determine a plurality of read requests based on the read access address; determine a hit on the table entry with the lookup key by issuing each of the read requests to the memory subsystem; and provide the hit on the table entry to the requesting entity or a next processing entity.
