CIRCUITS AND METHODS PROVIDING TEMPERATURE MITIGATION FOR COMPUTING DEVICES USING ESTIMATED SKIN TEMPERATURE

摘要

A method for temperature mitigation includes receiving a signal from a temperature sensor that is disposed within a computing device. A processor chip within the computing device produces heat. The signal from the temperature sensor is converted to temperature data. The method further includes processing the temperature data to generate an estimate of a temperature of an external surface of the device. The processing includes applying a low pass filter to the temperature data, applying an amplitude attenuation to the temperature data, and applying a delay to the temperature data. The method further includes reducing an operating parameter of the processor chip, such as operating frequency, in response to the estimated temperature of the external surface of the device.
