Abstract
In one embodiment, a temperature management system comprises a plurality of temperature sensors on a chip, and a temperature manager. The temperature manager is configured to receive a plurality of temperature readings from the temperature sensors, to determine a plurality of power values based on the temperature readings, to determine a plurality of temperature values based on the determined power values, the determined temperature values corresponding to a plurality of different locations on the chip, and to estimate a temperature of a hotspot on the chip based on the determined temperature values.
