Abstract
With the progress toward multi-core processors, each core is can not readily ascertain the status of the other dies with respect to an idle or active status. A proposal for utilizing an interface to transmit core status among multiple cores in a multi-die microprocessor is discussed. Consequently, this facilitates thermal management by allowing an optimal setting for setting performance and frequency based on utilizing each core status.
Claims8
A processor comprising:
- a plurality of cores,
- a turbo mode logic coupled to the plurality of cores to enable improved performance of the processor, at least in part, by increasing an operating frequency of at least one of the plurality of cores during a period in which at least one other of the plurality of cores is idle.
