主权项

1. A system comprising:
a plurality of processors; a first interconnect to communicatively couple at least two of the plurality of processors; a second interconnect to communicatively couple one or more of the processors to one or more other system components; and system memory communicatively coupled to one or more of the processors; at least one of the processors comprising:
a plurality of execution resources to process a plurality of threads;a cache to store instructions or data be shared by the plurality of execution resources;a first set of the plurality of execution resources to process a first set of one or more threads;a second set of the plurality of execution resources to process a second set of one or more threads;monitoring circuitry to detect an activity level and temperature associated with the plurality of execution resources;a power controller to scale frequency and voltage of the plurality of execution resources in accordance with specified constraints; anda thread management circuit to migrate a first thread from the first set of the plurality of execution resources to the second set of the plurality of execution resources.
