    • Dynamic power routing is utilized to route power from other components, which are transitioned to lower power consuming states, in order to accommodate more efficient processing of computational tasks by hardware accelerators, thereby staying within electrical power thresholds that would otherwise not have accommodated simultaneous full-power operation of the other components and such hardware accelerators. Once a portion of a workflow is being processed by hardware accelerators, the workflow, or the hardware accelerators, can be self-throttling to stay within power thresholds, or they can be throttled by independent coordinators, including device-centric and system-wide coordinators. Additionally, predictive mechanisms can be utilized to obtain available power in advance, by proactively transitioning other components to reduced power consuming states, or reactive mechanisms can be utilized to only transition components to reduced power consuming states when a specific need for increased hardware accelerator power is identified.
    • 动态功率路由用于将功率从其他组件转移到低功耗状态,以便通过硬件加速器来适应计算任务的更有效的处理,从而保持在电源阈值内,否则, 其他组件和这种硬件加速器的电源操作。 一旦工作流的一部分正在由硬件加速器处理,工作流程或硬件加速器可以自我调节以保持在电源阈值内,或者可以由独立协调器(包括以设备为中心的和全系统的协调器)进行限制 。 另外,可以利用预测机制来预先获得可用功率,主动地将其它组件转换到降低的功耗状态,或者当特定需要增加的硬件加速器功率时,反应机制可以仅用于将组件转换到降低的功耗状态 确定。
