Abstract: A method and apparatus of a device that manages system performance by controlling power state based on information related to I/O operations is described. The device collects historical I/O information. The historical I/O information may include the number of I/O operations over a sample period of time and the inter-arrival time between I/O operations. The device further receives information related to a current I/O operation. The information of the current I/O operation may include direction, size, quality of service, and media type of the I/O operation. The device determines a power state based on the historical I/O information and the information relative to the current I/O operation to reduce power consumption while improving system efficiency and maintaining an acceptable level of system performance. The device further applies the determined power state. Other embodiments are also described and claimed.

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.
