Abstract: Aiming at a new Monahans processor, this paper proposes a power management scheme combining with its own power management function and relative content of power management subsystem in Linux. The scheme can monitor system operating states in real time in order to dynamically decrease frequency and voltage of system operating, process conversion of power states. Application result proves that the scheme can decrease power of system, extend using time of battery.
