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.
Claims20
A processor comprising:
- a plurality of cores;
- a plurality of Thin-Film Thermoelectric Coolers (TFTECs) to dissipate heat from the processor;
- and
- a power manager to receive thermal information from one or more on-die thermal sensors, and to execute a control algorithm to:
- control a current supplied to at least one of the plurality of TFTECs based at least in part on the thermal information;
- identify a first core that has a first low-power thread;
- enable a first TFTEC that is allocated to the first core, wherein upon enablement the first TFTEC is to remove heat from the first core to produce a pre-cooled first core;
- and
- thereafter migrate a first high-power thread from a second core to the pre-cooled first core.

A multi-core processor comprising:
- a plurality of cores;
- a plurality of heat pumps each associated with at least one of the plurality of cores;
- and
- a power manager to execute a control algorithm to:
- identify a first core that has a first low-power thread;
- enable a first heat pump that is allocated to the first core, wherein upon enablement the first heat pump is to remove heat from the first core to produce a pre-cooled first core;
- and
- thereafter migrate a first high-power thread from a second core to the pre-cooled first core.
5 more elements
A system comprising:
- an antenna;
- a radio frequency (RF) transceiver coupled to the antenna;
- and
- a multicore processor coupled to the RF transceiver including:
- a plurality of cores and a plurality of Peltier devices each associated with at least one of the plurality of cores;
- and
- a power manager to:
- identify a first core that has a first low-power thread;
- enable a first Peltier device that is associated with the first core, wherein upon enablement the first Peltier device is to remove heat from the first core to
- produce a pre-cooled first core;
- and
- thereafter migrate a first high-power thread from a second core to the pre-cooled first core.
