Abstract
A device having multiple cores executes an algorithm to control Thin-Film Thermoelectric Coolers (TFTEC) that employ the Peltier effect to remove heat from the various cores of the multi-core processor. The algorithms may combine Thread Migration (TM) and Dynamic Voltage/Frequency Scaling (DVFS) to provide Dynamic Thermal Management (DTM) and TFTEC control.
Claims18
A processor comprising:
- a plurality of cores;
- a plurality of Thin-Film Thermoelectric Coolers (TFTECs) to dissipate heat from a circuit side of the processor to a backside of the processor;
- and
- a power manager to receive thermal information from on-die thermal sensors, activity information regarding the plurality of cores, and power and performance requirements of the processor, and to execute a control algorithm to administer a power change to the plurality of cores and to combine Thread Migration (TM), Dynamic Voltage and Frequency Scaling (DVFS), Dynamic Thermal Management (DTM) and TFTEC control.

A multi-core processor comprising:
- a plurality of cores;
- a plurality of Thin-Film Thermoelectric Coolers (TFTECs) associated with each core;
- and
- a power manager to execute a control algorithm to enable or disable the TFTECs associated with each core separate from the other cores, wherein the control algorithm is to combine Thread Migration (TM), Dynamic Voltage and Frequency Scaling (DVFS), and Dynamic Thermal Management (DTM).
1 more element
A system comprising:
- first and second antennas;
- a transceiver coupled to the first and second antennas;
- and
- a multi-core processor having a first core coupled to the transceiver and second and third cores with an array of Thin-Film Thermoelectric Coolers (TFTECs), wherein a control algorithm executed by the multi-core processor is to combine Thread Migration (TM) and Dynamic Voltage/Frequency Scaling (DVFS) to provide thermal management and control for the TFTECs.
