    摘要: Methods and apparatus to optimize package level power state usage are described. In one embodiment, a processor control logic receives a request to enter a lower power consumption state (such as a package level deeper sleep state). The control logic determines the time difference or delta between a last entry into the lower power consumption state and the current time. The control logic then causes the flushing of a last level cache based on a comparison of the time difference and a threshold value corresponding to the lower power consumption state. Other embodiments are also claimed and disclosed.

    摘要: Interconnect frequency control technologies of adjusting an operating frequency of a communication interconnect between an integrated circuit comprising multiple functional hardware units are described. A power management unit (PMU) is configured to collect workload data from the functional hardware units and determine a workload metric from the workload data. The PMU adjusts an operating frequency of the communication interconnect in view of the workload metric.
