Abstract: In one embodiment, the present disclosure provides a method capable of processing a variety of different operations. A method according to one embodiment may include loading configuration data from a shared memory unit into a hardware configuration register, the hardware configuration register located within circuitry included within a hardware accelerator unit. The method may also include issuing a command set from a microengine to the hardware accelerator unit having the circuitry. The method may additionally include receiving the command set at the circuitry from the microengine, the command set configured to allow for the processing of a variety of different operations. The method may further include processing an appropriate operation based upon the configuration data loaded into the hardware configuration register. Of course, many alternatives, variations and modifications are possible without departing from this embodiment.

Abstract: Method and apparatus for performing centralized cyclic redundancy checks (CRC). For one embodiment a current thread of execution compares a connection index with that of a previous thread of execution. If they share the same connection index, a CRC calculation may be performed without providing a CRC residue to a centralized CRC unit since the most recently produced CRC residue by would be associated with a preceding sequential cell of the same packet. For an alternative embodiment a current thread of execution requests a CRC calculation and provides a connection index to the centralized CRC unit, which is used to access a content addressable memory (CAM). A hit in the CAM indicates that the CRC unit may use the CRC residue associated with the connection index in the CAM since it would have resulted from a preceding sequential cell.
