ABSTRACT:
A frame-address matching function of a network controller is enhanced. In a full power-on mode, the controller performs conventional functions. In the low-power mode, the controller includes frame-address and frame-data matching, as well as pre-determined and programmable autonomous response to network protocol. If a match occurs with respect to the frame destination address or frame data, the system associated with the controller is placed in a wake-up state. If the controller is programmed to perform pattern matching inside the frame data area, upon such match in the frame data area the controller will generate and transmit on the network a simple response packet automatically. Conversely, if a match is not detected, no action is taken. The frame-data patterns are programmable with the capability to mask out certain data fields as desired which are protocol dependent and are substantially protocol dependent.
