In an embodiment, a processor includes a core domain with a plurality of cores and a power controller having a first logic to receive a first request to increase an operating voltage of a first core of the core domain to a second voltage, to instruct a voltage regulator to increase the operating voltage to an interim voltage, and to thereafter instruct the voltage regulator to increase the operating voltage to the second voltage. Other embodiments are described and claimed.

Controlling operating voltage of a processor

Methods, apparatus, and articles of manufacture to dynamically configure overclocking frequency have been disclosed. An example apparatus include a clock rate adjuster to cause a processor core to operate at a first overclocked clock rate; a comparator to compare a sensed temperature corresponding to the processor core to a threshold; and the clock rate adjuster to, when the sensed temperature satisfies the threshold, decrease a clock rate of the processor core from the first overclocked clock rate by a user-defined amount, the decreased clock rate being above a normal operating clock rate of the processor core.

Controlling operating frequency of a processor

Embodiments include apparatuses, methods, and systems including a power control unit to control different power consumptions by one or more processors to operate different applications. The power control unit may receive power information that may include a priority information for each application to be operated on the one or more processors, determine to control, based on the power information for different applications, different power consumptions by the one or more processors to operate the different applications. Other embodiments may also be described and claimed.

Application priority based power management for a computer device

A performance management scheme for a processor based on leakage current measurement in field. The scheme performs the operations of detection and correction. The operation of detection measures per core leakage current in the field (e.g., using voltage regulator electrical current counters). The operation of correction changes the processor power management behavior. For example, processor cores showing high leakage degradation may be logically swapped with cores showing low leakage degradation.

Leakage degradation control and measurement

A local power control arbiter is provided to interface with a global power control unit of a processing platform having a plurality of processing entities. The local power control arbiter controls a local processing unit of the processing platform. The local power arbiter has an interface to receive from the global power control unit, a local performance limit allocated to the local processing unit depending on a global power control evaluation and processing circuitry to determine any change to one or more processing conditions prevailing in the local processing unit on a timescale shorter than a duration for which the local performance limit is applied to the local processing unit by the global power control unit and to select a performance level for the local processing unit depending on both the local performance limit and the determined change, if any, to the prevailing processing conditions on the local processing unit.

Power control arbitration

Disclosed embodiments relate to processing logic for performing function operations. In one example, and apparatus includes an execution unit within a processor to execute a code block, power management hardware coupled to the execution unit, wherein the power management hardware is to monitor a first execution of the code block, store a micro-architectural context of the processor in a metadata block associated with the code block, the micro-architectural context including performance data resulting from the first execution of the code block, the performance data comprising power and energy usage data, and power management related parameters, read the associated metadata block upon a second execution of the code block, and tune the second execution based on the performance data stored in the associated metadata block to increase efficiency of executing the code block.

Mechanism for saving and retrieving micro-architecture context

In an embodiment, a processor includes a plurality of processing engines to execute instructions and a power management unit. The power management unit is to: control an operating frequency and a supply voltage according to a first voltage/frequency curve associated with a first temperature; and in response to a detection of a second temperature in the processor, increase the operating frequency to a second frequency based on a second voltage/frequency curve, wherein, at least one voltage of a first range of voltages, the second voltage/frequency curve specifies a higher frequency than the first voltage/frequency curve. Other embodiments are described and claimed.

In an embodiment, a processor includes processing engines to execute instructions and power limit logic. The power limit logic is to: in response to a plurality of power spikes, perform a number of soft throttling events and a number of hard throttling events in a first processing engine; determine a ratio of the soft throttling events to the hard throttling events; compare the determined ratio to a desired goal; and adjust one or more throttling parameters in response to a determination that the determined ratio does not match the desired goal. Other embodiments are described and claimed.
