A LOOK-ASIDE PROCESSOR UNIT WITH INTERNAL AND EXTERNAL ACCESS FOR MULTICORE PROCESSORS

A method and a system embodying the method for information lookup request processing at a look-aside processor unit entailing storing a received lookup transaction request in a first buffer; rebuilding the lookup transaction request into a request packet; transmitting the request packet; receiving a packet; determining whether the received packet is a response packet or an exception packet; and processing the received packet in accordance with the determining is disclosed. Furthermore, a method and a system embodying the method for exception packet processing at a look-aside processor unit entailing storing at least one received lookup transaction request in a first buffer; receiving a packet; determining that the received packet is an exception packet; and associating the exception packet with one of the at least one stored lookup transaction request in accordance with an identifier of the first buffer is disclosed.
