Abstract:
A method and apparatus of a device that manages a thermal profile of a device by selectively throttling central processing unit operations of the device is described. The device monitors the thermal profile of the device, where the device executes a plurality of tasks that utilizes a central processing unit of the device. In addition, the plurality of tasks includes a high QoS task and a low QoS process. If the thermal profile of the device exceeds a thermal threshold, the device increases a first CPU throttling for the low QoS task and maintains a second CPU throttling for the high QoS task. The device further executes the low QoS task using the first CPU utilization with the first processing core of the CPU by selectively forcing an idle of the low QoS task during an execution window. In addition, the device executes the high QoS task using the second CPU throttling with a second processing core of the CPU.
