Performance, thermal and power management system associated with an integrated circuit and related method

摘要

The performance, thermal and power management system is configured to perform DVFS calibration, temperature compensation adjustment, aging calibration, and DC offset calibration in an IC. The initial voltage supplied to the IC may be set to an initial value which takes chip-to-chip process variations into account and then dynamically adjusted according to temperature variations, DC offset and/or aging effects. Therefore, the performance, thermal and power management system may achieve optimized thermal and power performance of the IC.
