    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: The efficiency rating (ER) of each domain, in a processor, may be compared and then the power budget may be allocated, effectively, among the domains based on the ERs of the domains. The ER may indicate relative advantage among domains in terms of performance return for a given power budget, i.e., a higher effectiveness may be expected in power utilization if the ER is higher for a domain. The ER of a domain may be defined as (scalability factor/cost factor*alpha). The scalability factor may be defined as a performance increase (in %) brought about by an increase in the clock frequency (in %) provided to the domain. The cost factor may be defined as a power budget value required in bringing about an increase in the clock frequency provided to the domain and alpha is an adjustment factor.

    摘要: In one or more embodiments, a fixed time interval for a system is determined. The fixed time interval corresponds to time between clock ticks. A random time interval is determined based on the fixed time interval and an offset. One or more electronic components affixed to a motherboard are transitioned to a new power state when the random time interval has elapsed. By introducing a randomization to the timing element to a control signal that drives the power state transition, a periodicity for the system is disrupted. The disruption in periodicity mitigates acoustic noise generated by vibrations in electronic components and motherboards affected by current and/or voltage transitions.

    摘要: Power management of an embedded dynamic random access memory (eDRAM) using collected performance counter statistics to generating a set of one or more eDRAM effectiveness predictions. Using a set of one or more eDRAM effectiveness thresholds, each corresponding to one of the set of eDRAM effectiveness predictions, to determine whether at least one eDRAM effectiveness prediction has crossed over threshold. In the case that at least one eDRAM effectiveness prediction has crossed over its threshold, transitioning the eDRAM to a new power state. Power management is achieved by transitioning to a power-off state or self-refresh state and reducing the amount of power consumed by the eDRAM as compared to a power-on state.
