For one disclosed embodiment, a lower limit for a power consumption device may be identified. Performance of the power consumption device may be reduced in response to a determination that a temperature corresponding to the power consumption device exceeds a threshold. Performance reduction may be limited based on the lower limit. Other embodiments are also disclosed.

Performance reduction limit for power consumption device

Techniques to manage operational parameters for a processor are described. For instance, a method includes monitoring performance values representing physical characteristics for multiple components of a computing platform, and managing a performance level for a processor based on the performance values and one or more operational parameters for the processor. The operational parameters may include one or more transitory operational parameters that cause the processor to temporarily exceed operational parameters set by a thermal design power limit. Other embodiments are described and claimed.

Techniques to manage operational parameters for a processor

Methods and apparatuses for intervening in the self power or thermal regulations of a plurality of independent power consumption devices are described herein. The novel methods may include monitoring power consumption and thermal conditions of the plurality of power consumption (i.e., power/heat dissipation) devices that are configured to independently self-regulate their power/thermal production. A determination may then be made as to whether an aggregate of the power and/or thermal production of the plurality of power consumption devices exceed a threshold. And if the aggregate of the power or thermal production of the power consumption devices was determined to exceed the threshold, terminating, at least partially, the independent self-regulating of the thermal production and intervening in the thermal regulation of one or more of the power consumption devices. In contrast, if the aggregate of the power and/or thermal production of the plurality of power consumption devices is determined to be below the threshold then the power consumption devices may be allowed to self-regulate their power consumptions, and in some instances, one or more of the individual power clamps for the one or more of the power consumption devices may be relaxed or raised.

Intervention of independent self-regulation of power consumption devices

A system for measuring and managing thermal operations of a processor core on a semiconductor die using a sensor positioned in a hotspot of the processor core. A measured temperature reading is determined based upon a temperature sensed by the sensor. Interrupt signals and a software readable register indicating temperature information provide feedback about the thermal environment to the processor. Based upon the measured temperature reading, the interrupt signals direct the processor to modify operation.

Device and method for on-die temperature measurement

A method of creating a thermal influence table to describe thermal relationships between components in a system and use of the thermal influence table in a system is described. The thermal influence matrix may be generated dynamically for a system. The matrix may be used by a thermal management policy to enable a hot device to be cooled by power management of another device in the system.

Determining the thermal influence of components within a system and usage of a matrix for power and thermal management

A method and apparatus for measuring the temperature of a computer system, such as a notebook computer, is described. A sensor module is to mount within the computer system spaced from an interior surface of a chassis of the system, the sensor to measure an internal surface of a chassis of the system.
