Method, apparatus, and system for optimizing frequency and performance in a multidie microprocessor

摘要

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.

1. A processor comprising:
a plurality of cores each including clock generation circuitry and a phase locked loop; and a control logic to increase an operating frequency of at least one of the plurality of cores during a turbo mode in which at least one other of the plurality of cores is idle, wherein the at least one other of the plurality of cores is to communicate a core power status to the at least one core via a link interface.
