20080244287 | Platform communication protocol - A host chipset heartbeat may be utilized, in some embodiments, to handle interrupts from external devices on a power efficient basis. The availability of the host chipset heartbeat may be signaled to external devices and those external devices may time their activities to a period of time when not only are resources available, but the assertion of the activity is advantageous because the host chipset is already transitioning from a lower power consumption state. | 10-02-2008 |
20090089606 | Opportunistic initiation of data traffic - A method for trafficking data based at least in part on a power condition of a system resource. In one embodiment of the invention, a data trafficking device initiates data traffic in response to a detecting of an indication of the power condition. In another embodiment of the invention, the detected indication is independent of any data traffic of the data trafficking device. | 04-02-2009 |
20090164818 | ACTIVITY WINDOW NOTIFICATION PROTOCOL - Power management protocols for maximizing energy efficiency in power usage by mobile devices are described in this application. The power management protocols may allow for at least two power states by a CPU—active state, and inactive state. The active state corresponds to an active window when the mobile device is functional at full capacity and using the full clock speed frequency. The inactive state and opportunistic flush and fill states may be maximized by coordinating the activity of the CPU and other devices associated with a mobile device such as a bus, memory, graphics controller, hard drive, etc. By coordinating the critical functions of devices and CPU to occur during the active window, and delaying non-critical functions until an active window, the inactive and off states may be maximized, resulting in power savings and efficiency. Other embodiments are also described in this application. | 06-25-2009 |
