摘要：
Methods and apparatuses to dynamically manage a performance state of a data processing system are described. The data processing system includes a plurality of components; one or more buses coupled to the plurality of components, and a dynamic performance state manager unit coupled to the components. The dynamic performance state manager unit is configured to receive information about a first plurality of current states of components of the system. The dynamic performance state manager unit is configured to determine a second plurality of required system performance states for the components; and to determine a current system performance state based on the first plurality and the second plurality.
