摘要
本文提出了设备利用率的概念,并根据设备利用率的高低确定设备的电源状态,分别给出了三个临界条件。最后对电源状态的转换条件进行了优化,优化处理后待机态的能耗节省了21%。
A conception of the device utilization ratio is present here. We give out three different critical conditions according to the power state of the device by the device utilization ratio. The energy consumption at stand-by state can be reduced by 21% after the optimization of the switchover condition.
