Look-aside processor unit with internal and external access for multicore processors

摘要

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.

1. A method for information lookup request processing at a look-aside processor unit, comprising:
storing a received lookup transaction request in a first look-aside buffer of a first storage; rebuilding the lookup transaction request into a request packet; transmitting the request packet; receiving a packet; comparing ternary values of specific bits in the received packet with ternary values of bits in a pre-determined mask; determining the received packet to be a response packet when the bits in the received packet disagree with the bits in the pre-determined mask; and determining the received packet to be an exception packet when the specific bits in the received packet agree with the bits in the pre-determined mask; and processing the received packet in accordance with the determining.
