Abstract
In one embodiment, a temperature management system comprises a plurality of thermal sensors at different locations on a chip, and a temperature manager. The temperature manager is configured to receive a plurality of temperature readings from the thermal sensors, to fit a quadratic temperature model to the received temperature readings, and to estimate a hotspot temperature on the chip using the fitted quadratic temperature model.
