摘要： A power management unit (PMU) may promote a processing core from a working state to a first non-working power saving state after receiving a signal from an automatic core C-state promotion (ACCP) unit. An OS component may detect the idling of the processing core and may initiate the ACCP. The ACCP may initiate the PMU to promote the processing core to a first non-working power saving state. The ACCP may track the residency time of the processing core in the first non-working power saving state and may initiate the PMU to promote the processing core to a next non-working power saving state if residency time of the processing core in the first non-working power saving state exceeds a first value. The ACCP may initiate the PMU to demote the processing core back to the working state if a break event occurs during the residency time.
摘要翻译：电力管理单元（PMU）可以在接收到来自自动核心C状态提升（ACCP）单元的信号之后将处理核心从工作状态提升到第一非工作省电状态。 OS组件可以检测处理核心的空闲并且可以启动ACCP。 ACCP可以启动PMU以将处理核心提升到第一非工作省电状态。 ACCP可以在第一非工作省电状态下跟踪处理核心的驻留时间，并且如果处理核心在第一非工作省电状态中的驻留时间，则可以启动PMU以将处理核心升级到下一个非工作省电状态 - 省电状态超过第一个值。如果在驻留时间内发生中断事件，则ACCP可以启动PMU将处理核心降级到工作状态。

摘要： A method, system, and apparatus may route an interrupt to a first core of a plurality of cores of a multi-core system. If the first core is in an idle or low power state, or operating in a power state at or below a threshold power state, a core in a least idle state may be found. The interrupt may be rerouted to and processed by the core in the least idle state. Cores in a multi-core system may be rated based on for example, power states or other characteristics, and interrupts may be assigned based on these ratings. Other embodiments are described and claimed.
