Abstract
A method for dynamically operating a multi-core processor system is provided. The method involves ascertaining currently active processor cores, identifying a currently active processor core having a lowest operating frequency, and adjusting at least one operational parameter according to voltage-frequency characteristics corresponding to the identified processor core to fulfill a predefined functional mode, e.g. power optimization mode, performance optimization mode and mixed mode.
