Abstract: The invention provides a technique for targeted scaling of the voltage and/or frequency of a processor included in a computing device. One embodiment involves scaling the voltage/frequency of the processor based on the number of frames per second being input to a frame buffer in order to reduce or eliminate choppiness in animations shown on a display of the computing device. Another embodiment of the invention involves scaling the voltage/frequency of the processor based on a utilization rate of the GPU in order to reduce or eliminate any bottleneck caused by slow issuance of instructions from the CPU to the GPU. Yet another embodiment of the invention involves scaling the voltage/frequency of the CPU based on specific types of instructions being executed by the CPU. Further embodiments include scaling the voltage and/or frequency of a CPU when the CPU executes workloads that have characteristics of traditional desktop/laptop computer applications.

Abstract: The embodiments set forth a technique for providing reactive performance throttle engagement information to controller limiters, which are implemented as closed loop structures that analyze the information against target reactive performance throttle engagement rates and produce control effort limits. When reactive performance throttle engagement rates are below the target, controllers issue control efforts in a normal fashion such that they are not influenced by the control effort limits produced by the controller limiters. However, the controller limiters are also configured such that when reactive performance throttle engagement rates are above the target, the controllers issue control efforts in a modified fashion—specifically, in accordance with the control effort limits produced by the controller limiters. In this manner, control effort limits can effectively clamp the control efforts when particular conditions—such as excessive reactive performance throttle engagement rates—are being met.

Abstract: A device implementing adaptive memory performance control by thread group may include a memory and at least one processor. The at least one processor may be configured to execute a group of threads on one or more cores. The at least one processor may be configured to monitor a plurality of metrics corresponding to the group of threads executing on one or more cores. The metrics may include, for example, a core stall ratio and/or a power metric. The at least one processor may be configured to determine, based at least in part on the plurality of metrics, a memory bandwidth constraint with respect to the group of threads executing on the one or more cores. The at least one processor may be configured to, in response to determining the memory bandwidth constraint, increase a memory performance corresponding to the group of threads executing on the one or more cores.

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: The embodiments set forth a technique for targeted scaling of the voltage and/or frequency of hardware components included in a mobile computing device. One embodiment involves independently analyzing the individual frame rates of each animation within a user interface (UI) of a mobile computing device instead of analyzing the frame rate of the UI as a whole. This can involve establishing, for each animation being displayed within the UI, a corresponding performance control pipeline that generates a control signal for scaling a performance mode of the hardware components (e.g., a Central Processing Unit (CPU)) included in the mobile computing device. In this manner, the control signals generated by the performance control pipelines can be aggregated to produce a control signal that causes a power management component to scale the performance mode(s) of the hardware components.
