摘要:
A method and apparatus for executing a first executable code image having a first version number into a memory of a device in an attempt to establish an operating environment of the device are described. The first executable code image retrieves a second version number from the second executable code image after successfully authenticating the second executable code image. If the first version number and the second version number do not satisfy a predetermined relationship, the second executable code image is prevented from being loaded by the first executable code image.

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.
