For example, a power-setting controller may be configured to provide a power setting for a processor based on one or more sensor-based inputs corresponding to one or more temperature sensors. For example, a sensor-based input corresponding to a temperature sensor may include a temperature input and a target temperature. For example, the power-setting controller may include one or more NNPID-based power controllers configured to provide one or more sensor-based power settings corresponding to the one or more temperature sensors. For example, an NNPID-based power controller of the NNPID-based power controllers may be configured to provide a sensor-based power setting corresponding to the temperature sensor based on the sensor-based input corresponding to the temperature sensor. For example, the NNPID-based power controller may include an NNPID controller configured to determine a temperature setting based on the temperature input and the target temperature corresponding to the temperature sensor.

Apparatus, system and method of providing a power setting for a processor

Methods, apparatus, systems and articles of manufacture for power sharing between discrete processors are disclosed. An example apparatus includes a thermal monitor to monitor temperatures of first and second discrete processors and a balance controller to, in response to a first temperature of the first processor satisfying a temperature threshold, adjust first and second power budgets allocated to the respective first and second processors.

Methods and apparatus for power sharing between discrete processors

In one embodiment, a processor includes: at least one core; and a power controller coupled to the at least one core. The power controller may include: a workload monitor circuit to calculate a background task ratio based on a first amount of time that the at least one core executed background tasks during an active duration; and a control circuit to dynamically apply a power management policy for a background mode when the background task ratio exceeds a background mode threshold, the power management policy for the background mode to reduce power consumption of the processor. Other embodiments are described and claimed.

System, apparatus and method for dynamically adjusting platform power and performance based on task characteristics

Disclosed Methods, Apparatus, and articles of manufacture to dynamically enable and/or disable prefetchers are disclosed. An example apparatus include an interface to access telemetry data, the telemetry data corresponding to a counter of a core in a central processing unit, the counter corresponding to a first phase of a workload executed at the central processing unit; a prefetcher state selector to select a prefetcher state for a subsequent phase based on the telemetry data; and the interface to instruct the core in the central processing unit to operate in the subsequent phase according to the prefetcher state.

Methods and apparatus to dynamically enable and/or disable prefetchers

In one embodiment, a method receives data regarding processing of a workload by a processor. The data is input into a prediction engine configured to classify the data into a plurality of workload classifications. Each workload classification describes different temporal behavior of the workload. Then, the method outputs a prediction for at least one of the plurality of workload classifications, wherein the prediction is used to control performance of the processor in an upcoming period of time.

Classification prediction of workload thermal behavior

Aspects of the embodiments are directed to systems, methods, and program products for rebalancing power in a multi-chip computing platform, which includes a core processor and a discrete peripheral processor. Embodiments include determining that the core processor and the discrete peripheral processor are in a limited usage state; altering a polling interval of the core processor and the discrete peripheral processor from a first polling time to a second polling time, the second polling time greater than the first polling time; and polling the core processor and the discrete peripheral processor after an expiration of the second polling time. Embodiments also include using thermal and/or energy consumption data to dynamically adjust polling times to permit the core processor and the discrete peripheral processor to remain in an idle or low power state for as long as possible.
