ABSTRACT:
A method and system for transferring control information between a host and network processor is provided. The system includes, a snooping module that is coupled to a snooping memory bus; a network cache controller; a host process scheduler that communicates with the network cache controller; and a host cache controller that controls a host cache for transferring control information without polling.The method includes, invalidating a data block in a network cache, after a message is composed by the host processor; invalidating a status block in the network cache after the message is posted; and transferring control from the host processor to the network processor. The method also includes, invalidating a status segment in a network cache after data is transferred from a host cache to a network cache; and invalidating a status segment in the host cache after data has been injected to a network.
