Abstract
A communication processor comprises a data link layer parser circuit () and a plurality of network layer parser circuits (). The data link layer parser circuit () receives a data link layer frame, and removes a data link layer header therefrom to provide a network layer frame as an output. Each network layer parser circuit corresponds to a different network layer protocol, and is selectively activated to receive the network layer frame and to process a network layer header therefrom to provide a transport layer frame as an output. The data link layer parser circuit () further examines a portion of the network layer frame to determine which of the plurality of network protocols is used. The data link layer parser circuit () activates a corresponding one of the plurality of network layer parser circuits () in response, while keeping another one of the plurality of network layer parser circuits () inactive.
