In one embodiment, the present invention includes an apparatus having a first processor to execute instructions, a subordinate processor coupled to the first processor, and multiple physical devices coupled to the subordinate processor. The physical devices may each correspond to a different network communication protocol, and may each include a physical unit to forward packets to the subordinate processor while the system is in a low power mode. The subordinate processor may remain enabled during the low power mode and may include media access control functionality for handling incoming packets of different physical devices.
