    摘要： Power management of an embedded dynamic random access memory (eDRAM) by receiving an eDRAM power state transition event and determining both the current power state of the eDRAM and the next power state of the eDRAM from the power states of: a power-on state, a power-off state, and a self-refresh state. Using the current power state and the next power state to determine whether a power state transition is required, and, in the case that a power state transition is required, transition the eDRAM to the next power state. Power management is achieved because transitioning to a power-off state or self-refresh state reduces the amount of power consumed by the eDRAM as compared to the power-on state.

    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.
