Google patents chip cooling that predicts heat before it happens

Patent drawing
Patent drawing from the official filing.

Google has filed a patent for a system that predicts how hot a computer chip will get before it actually happens. It uses these predictions to adjust the chip's speed and power usage early, keeping the device from getting too hot to the touch.

Why it mattersThis could make phones and laptops stay cooler during heavy use, improving comfort and potentially extending battery life.

In the filing’s own words

Techniques and apparatuses are described for implementing proactive thermal control for a system-on-chip. In example aspects, a thermal-control system utilizes a prediction model to predict a future evolution of an SoC based on a current operation point and a current temperature of the SoC. The prediction is used to proactively update a thermal-control policy that manipulates an operation point of one or more subsystems of the SoC. In aspects, a user perception of a thermal limit to an enclosure (e.g., surface temperature of a surface of the enclosure that the user touches) of a device having the SoC is also used to determine tradeoffs and contradicting goals between the calculated power/thermal metrics for the device and the user's perception of the thermal limit for the enclosure (e.g., surface temperature that the user touches).

What exactly they claim (claim 1)

1. A method performed by a system-on-chip, the method comprising: obtaining, by a thermal-control system of the system-on-chip, a prediction indicating an estimation of a future temperature of a subsystem of the system-on-chip based on a current operation point and a current temperature of the subsystem; generating, by a policy adjustor of the thermal-control system and based on the prediction, a thermal-control policy for a controller associated with the subsystem, the thermal-control policy defining a temperature target and a cadence for the controller; determining, by the controller, a new operation point for the subsystem based on the thermal-control policy; and enforcing, by the subsystem, the new operation point for proactive thermal mitigation.
