Abstract: Circuits, methods, and apparatus that may estimate the power being consumed by an OLED display screen of an electronic device, may provide further information about that power usage, may modify or change functions performed by the electronic device based on that power usage, and may inform an application's developer about the amount of power being used by the electronic device while the electronic device is running the application. One example may estimate the power being used by an OLED display screen of an electronic device by determining the content of images being displayed during a duration. The estimated power may then be presented to a user. The estimated power may be used in decisions to modify or change parameters of the screen or other device components.

Abstract: In one embodiment, a system includes power management control that controls a duty cycle of a processor to manage power. The duty cycle may be the amount of time that the processor is powered on as a percentage of the total time. By frequently powering up and powering down the processor during a period of time, the power consumption of the processor may be controlled while providing the perception that the processor is continuously available. For example, the processor may be a graphics processing unit (GPU), and the period of time over which the duty cycle is managed may be a frame to be displayed on the display screen viewed by a user of the system.
Abstract translation: 在一个实施例中，系统包括控制处理器管理电力的占空比的电源管理控制。 占空比可以是处理器上电的时间量占总时间的百分比。 通过在一段时间内频繁地加电和断电处理器，可以控制处理器的功耗，同时提供处理器持续可用的感知。 例如，处理器可以是图形处理单元（GPU），并且管理占空比的时间段可以是要在系统的用户观看的显示屏上显示的帧。

Abstract: The subject matter of the disclosure relates to low temperature power throttling at a mobile device to reduce the likelihood of an unexpected power down event in cold weather environments. A mobile device employing a power management solution may be configured to determine that a monitored temperature at the mobile device (at the battery of the mobile device) is below a first threshold level, and whether a hardware component (such as a camera) is active or inactive. Then, based on these determinations, the mobile device can select a throttle setting from a first set of throttle settings when the hardware component is active, and a second set of throttle settings when the hardware component is inactive. Subsequently the mobile device can throttle power consumption for one or more components of the mobile device according to the selected throttle setting.

Abstract: In one embodiment, a system controls a duty cycle of a processor (e.g. a graphics processing unit (GPU)) to manage power. The GPU may include a snoop indicator that may control whether or not the GPU captures and/or responds to communications from another processor (e.g. a central processing unit (CPU) that executes a driver associate with the GPU). A snooze indicator may control whether or not the GPU is automatically repowered at the start of the next frame, or is repowered only if the communication indicating additional work has been received. In an embodiment, the GPU mode controls discussed above may permit the GPU firmware executed with the GPU itself to control duty cycle power down, independent of the driver executing on the CPU.
