摘要： Embodiments are presented herein of, inter alia, systems, devices, and associated methods for allocating and distributing power management budgets for classes of tasks being executed by a computer system, based on thermal feedback loops. Specifically, multiple quality-of-service (QoS) tiers may be defined, and each QoS tier may be allocated power based on a different set of thermal feedback loops. QoS tiers including tasks that are invisible to the user may be mitigated more aggressively than QoS tiers including tasks that are visibly supporting user operations.

摘要： Systems and methods are disclosed for determining a current machine state of a processing device, predicting a future processing task to be performed by the processing device at a future time, and predicting a list of intervening processing tasks to be performed by a first time (e.g. a current time) and the start of the future processing task. The future processing task has an associated initial state. A feed-forward thermal prediction model determines a predicted future machine state at the time for starting the future processing task. Heat mitigation processes can be applied in advance of the starting of the future processing task, to meet the future initial machine state for starting the future processing task.

摘要： 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.
