Apparatus and method for dynamically adjusting platform power and performance based on task characteristics

The invention relates to an apparatus and method for dynamically adjusting platform power and performance based on task characteristics. In one embodiment, a processor comprises: at least one core; and a power controller coupled to the at least one core. The power controller may include a workload monitor circuit to calculate a background task ratio based on a first amount of time when the at least one core has executed a background task during an active duration; and control circuitry to dynamically apply a power management policy for the background mode when the background task ratio exceeds a background mode threshold, the power management policy for the background mode to reduce power consumption of the processor. Other embodiments are described and claimed. 本公开涉及用于基于任务特性动态调整平台功率和性能的装置和方法。在一个实施例中，一种处理器包括：至少一个核心；以及耦合到至少一个核心的功率控制器。功率控制器可包括：工作负载监视器电路，用于基于至少一个核心在活跃持续时间期间执行了后台任务的第一时间量来计算后台任务比率；以及控制电路，用于在后台任务比率超过后台模式阈值时动态地应用用于后台模式的功率管理策略，用于后台模式的功率管理策略用于降低处理器的功率消耗。描述和要求保护了其他实施例。
