Abstract
Adaptive power capping in a chip that includes a plurality of cores in a processing system is provided. An active power demand for the chip is dynamically determined based on observed events of the cores. An average temperature of the chip is computed using one or more on-chip thermal sensors in the cores to estimate leakage power of the chip. A power capping threshold that incorporates the estimate of leakage power is determined based on the average temperature of the chip. Power capping is performed by throttling the cores based on determining that the active power demand for the chip exceeds the power capping threshold.
