From the background information supplied by the inventors, news correspondents obtained the following quote: "Electronic devices are ubiquitous in society and can be found in everything from wristwatches to cellular telephones. With the proliferation of integrated circuitry, these electronic devices are becoming more and more sophisticated. Some electronic devices may include systems-on-a-chip (SOCs) that may integrate different components associated with the various functions of the electronic device into a single integrated circuit. As part of this trend toward increasing sophistication, many of the SOCs often need to communicate with each other as well as communicate with other integrated circuits external to the electronic devices.
"Another growing trend with electronic devices is increasing power consumption. Generally, electronic devices often consume greater power than their predecessors, in part due to their increasing levels of functionality. In the case of mobile electronic devices, such as laptops and/or cellular telephones, increased power consumption may be detrimental because it may consume precious battery life. These power problems are exacerbated when the mobile electronic device also includes radio capabilities, such as Bluetooth, WiFi.TM., and so on. Many mobile electronic devices contain radio capabilities.
"Accordingly, there is a need for providing power management to electronic devices implementing SOCs and that have radio capabilities."
Supplementing the background information on this patent, VerticalNews reporters also obtained the inventors' summary information for this patent: "Apparatuses and methods are disclosed for implementing an inter-processor communication channel including power-down functionality. In one embodiment, the apparatus may include a first integrated circuit (IC), and a second IC coupled to the first IC via a communication interface, wherein the first IC may occupy one or more low power states during which it does not monitor the communication interface. The apparatus may further include an inter-processor communication (IPC) channel coupled between the first and second ICs. The IPC channel may be separate from the communication interface, further the second IC may generate at least one advisory signal, and transmit such a signal to the first IC via a sideband of the IPC channel.
"Another embodiment may include a method of managing power within an electronic device. The method may include the operations of monitoring at least one transmission signal on an interface, monitoring at least one receive signal on the interface, delaying a synchronization signal on the interface and concurrently determining whether data is present on the at least one transmission signal or present on the at least one receive signal, and, in the event that the determination is positive, selectively entering a low power state of the electronic device after a synchronization signal has been received.
"Another embodiment may include a computer system, comprising a central processing unit (CPU), a memory coupled to the CPU, a system on a chip (SOC) coupled to the CPU, a radio coupled to the SOC using a serial-media-independent-interface (SMII), the radio comprising a clock generator, wherein the clock generator provides a synchronous timing signal to the SMII, and a power management unit (PMU) coupled to both the SOC and the radio, wherein the PMU is configured to provide an advisory power down signal to the SOC as directed by the radio."
