Abstract
A method offloading data intensive tasks from a processor comprises receiving at a configurable logic device (CLD) a network packet, parsing the network packet to determine that the packet is a TCP segment, searching a partially assembled packet table to locate an associated partially assembled packet data structure, inserting the network packet into the associated partially assembled packet data structure, recognizing that the partially assembled packet data structure contains every segment produced from an original TCP packet, assembling a fully assembled TCP packet from the data in the partially assembled packet data structure, and transmitting the fully assembled TCP packet to a processor in the same computer system as the CLD.
