ABSTRACT:
An apparatus and method for controlling a supply voltage using hierarchical performance monitors includes a signal generator generating an operating frequency and a target operating frequency, a supply voltage generator generating the supply voltage, a plurality of local performance monitors, and a global performance monitor. Each of the plurality of local performance monitors implemented in each different domain is modelled on a relationship between a level of the supplied voltage supplied to each different domain of a predetermined system and an operating speed or the operating frequency of a predetermined circuit implemented in the interior of the domain. The plurality of local performance monitors, respectively, monitors continuously whether the level of the supply voltage supplied to the domain is suitable for the target operating frequency, and outputs a local feedback signal. The global performance monitor generates the global feedback signal based on the local feedback signals of the plurality of local performance monitors, the supply voltage generator adjusts the level of the supply voltage based on the global feedback signal, and the signal generator changes the operating frequency to the target operating frequency when the level of the supply voltage corresponds to the target operating frequency.
