Abstract
Techniques are disclosed relating to power management of an integrated circuit. In one embodiment, an integrated circuit includes a plurality of temperature sensors configured to measure a plurality of temperatures at different locations in the integrated circuit. The integrated circuit further includes a power management circuit configured to determine a set of guard bands based on a temperature difference determined using the plurality of temperatures. The power management circuit is configured to adjust, using the set of guard bands, a particular one of the plurality of temperatures, and to use the adjusted particular temperature to manage power consumption of the integrated circuit. In some embodiments, the power management circuit is configured to manage the power consumption by adjusting a voltage supplied to the integrated circuit, the adjusted voltage being based on the adjusted particular temperature.
