Low power state selection based on idle duration history

An apparatus (100) includes a processor (102), a sleep state duration prediction module (404), and a system management unit (316). The sleep state duration prediction module is configured to predict a sleep state duration (416) of a component of the device. The system management unit transitions the component to a sleep state selected from a plurality of sleep states based on a comparison of the predicted sleep state duration to at least one duration threshold. Each sleep state of the plurality of sleep states is a state of lower power than a previous sleep state of the plurality of sleep states. 本发明涉及一种装置(100)，该装置包括处理器(102)、睡眠状态持续时间预测模块(404)和系统管理单元(316)。该睡眠状态持续时间预测模块被配置为预测该装置的部件的睡眠状态持续时间(416)。该系统管理单元基于预测的睡眠状态持续时间与至少一个持续时间阈值的比较，将该部件转变成选自多个睡眠状态的睡眠状态。该多个睡眠状态中的每个睡眠状态是比该多个睡眠状态中的先前睡眠状态功率更低的状态。
