Abstract
A processor includes a plurality of exclusive resources, a shared resource, and a controller configured to manage power state transitions of each of the plurality of exclusive resources and the shared resource. The controller receives a request from a resource to transition from a first power state to a lower power state and, in response to receiving the request, the controller controls power state transitions of the resource according to a first power control threshold when the resource is one of the plurality of exclusive resources and according to a second power control threshold that is greater than the first power control threshold when the resource is the shared resource.
