Abstract
A power management system schedules the voltage and frequency of processors in a data processing system based on two criteria. The first criterion is a prediction of the performance that the work currently running on the processor will experience at the different frequencies that are available. The second criterion is a system-wide constraint on the total power budget allocated to processors. Based on these criteria, low-level code sets the frequency and voltage of the processors in the system to match what the operating system is currently running on them.
