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 |
