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.
