    摘要: Techniques described above may enhance the power-performance efficiency of a processor, SoC, or a computing system. Embodiments described here allow an increase in frequency of the clock signal to a peak frequency value in response to detecting an occurrence of a burst of high activity within the low processor utilization periods. A power management unit may accumulate the budget during the low or idle processor utilization periods and the level of activity of the burst of high activity signal may be determined. The PMU may increase the frequency of the clock signal provided to the processing cores if the level of the burst of high activity exceeds a first threshold value and an accumulated budget value exceeds a second threshold value.

    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.
