Abstract: A method and apparatus for exiting a low power state based on a prior prediction is disclosed. An integrated circuit (IC) includes a functional unit configured to, during operation, cycle between intervals of an active state and intervals of an idle state. The IC also include a power management unit configured to place the functional unit in a low power state responsive to the functional unit entering the idle state. The power management unit is further configured to preemptively cause the functional unit to exit the low power state at a predetermined time after entering the low power. The predetermined time is based on a prediction of idle state duration made prior to entering the low power state. The prediction may be generated by a prediction unit, based on a history of durations of intervals in which the functional unit was in the idle state.

Abstract translation: 公开了一种基于先前预测退出低功率状态的方法和装置。 集成电路（IC）包括功能单元，其被配置为在操作期间在活动状态的间隔和空闲状态的间隔之间循环。 IC还包括电源管理单元，其被配置为响应于功能单元进入空闲状态而将功能单元置于低功率状态。 电源管理单元还被配置为在进入低功率之后的预定时间，预先使功能单元退出低功率状态。 预定时间基于在进入低功率状态之前进行的空闲状态持续时间的预测。 预测可以由预测单元基于功能单元处于空闲状态的间隔的持续时间的历史来生成。
