Hardware-based packet address parsing for packet reception in wireless networks

An apparatus comprises a network physical layer and an activity sensor for sensing a packet and activating the network physical layer from shutdown. The network physical layer decodes a PHY header portion and a media access control header portion of a packet header. A MAC has a fixed hardware media...

Zusammenfassung:	An apparatus comprises a network physical layer and an activity sensor for sensing a packet and activating the network physical layer from shutdown. The network physical layer decodes a PHY header portion and a media access control header portion of a packet header. A MAC has a fixed hardware media access plane implementing IEEE 802.11 series MAC functionality and couples to a microprocessor. A MAC address parser receives the MAC header portion of the packet, for processing the MAC header portion of the packet, and for activating the MAC from a shutdown in response to recognizing a MAC address within the MAC header portion of the packet, such that the MAC is not activated if the MAC parser does not recognize the MAC address, wherein the MAC is operable, after activation, to perform MAC functionality without the microprocessor and to provide data from the packet to the microprocessor.
