Microarchitecture controller for thin-film thermoelectric cooling

摘要

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.

主权项

1. 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; andthereafter migrate a first high-power thread from a second core to the pre-cooled first core.
