Abstract
A system may include a first portion and a processor. The first portion may include a first thermal sensor to provide first thermal data. The processor may include a core, a core thermal sensor to provide core thermal data, and an electrical power sensor to provide electrical data. The processor may also include a power management unit to selectively throttle the core based on the first thermal data, the core thermal data, and the electrical data.
Claims25
An apparatus, comprising:
- a processor core;
- a thermal sensor proximate to the processor core;
- an electrical power sensor proximate to the processor core;
- and
- a power management unit to control the processor core based on a thermal power threshold and an electrical power threshold that is different from the thermal power threshold.

A system, comprising:
- a first portion, including:
- a first thermal sensor to provide first thermal data;
- a processor, including:
- a core,
- a core thermal sensor to provide core thermal data,

4 more elements
A method, comprising:
- checking first thermal data from a first component;
- reading second thermal data from a second component;
- examining electrical data from the second component;
- and
- selectively reducing power consumption of the second component based on the first thermal data, the second thermal data, and the electrical data.
2 more elements
A method, comprising:
- checking first thermal data from a first portion;
- reading second thermal data from a processor;
- examining electrical data from the processor;
- decreasing power consumption of the processor if the first thermal data exceeds a first threshold, if the second thermal data exceeds a second threshold, or if the electrical data exceeds third threshold;
- and
- increasing power consumption of the processor if the electrical data is lower than a fourth threshold.
