Patent ID: 6985755

Claim:
An integrated circuit that services communications between a wirelessly enabled host and at least one user input device, the integrated circuit comprising: a wireless interface unit that wirelessly interfaces wit the wirelessly enabled host; a processing unit operably coupled to the wireless interface unit; an input/output unit operably coupled to the wireless interface unit and to the processing unit, wherein the input/output unit also operably couples to the at least one user input device; and a power management unit operably coupled to the wireless interface unit, the processing unit, and the input/output unit, wherein the power management unit controls the power consumption of the integrated circuit by: assisting the processing unit in entering one of a power down mode and an idle mode, wherein in the idle mode, the wireless interface unit performs first power conserving operations such that the wireless interface unit does not transmit to the wirelessly enabled host, and the wireless interface unit listens to the transmissions of the wirelessly enabled host; and receiving notification from the input/output unit that indicates activity by the at least one user input device; and causing the processing unit to exit the power down mode or the idle mode in response to the notification.
