Abstract: Adaptive CPU power limit tuning can be performed. A mode detector can employ a machine learning model to detect a mode of operation on a computing device. As the computing device operates in the various modes, a mode boundary tuner of the mode detector can evaluate performance measurements to determine whether the currently defined boundaries between the various modes are optimal for the particular computing device.

As the computing device operates in a mode, a power limit tuner can evaluate performance measurements and adjust the power limits to thereby tune the mode-specific power limits to the workload that is currently being executed.

Abstract: Integrated circuits (ICs)—depending on a current workload—may exceed thermal cooling budgets. As a result, ICs often implement thermal sensors to measure temperatures at junctions or hot spots along the IC. Due to a distance between the thermal sensors and the various junctions, a thermal offset may be added to the temperature readings from the thermal sensors to more accurately estimate the temperature at the junctions. To account for different workload distributions—e.g., asymmetric or symmetric—the systems and methods described herein may dynamically adjust the thermal offsets. As a result, the efficiency of the IC may be increased as thermal settings for the IC may take into account the ability of the thermal cooling budget to effectively cool the IC under a current operating condition—thereby reducing premature throttling back or shutting down of power to the IC.
