Abstract: A multi-core processor system and method are provided. The multi-core processor system includes a plurality of processor cores and a task scheduler. The processor cores perform a plurality of tasks, wherein each of the tasks is in a respective one of a plurality of scheduling classes. The task scheduler obtains first task assignment information about tasks which are in a first scheduling class from the scheduling classes and assigned to the processor cores, obtains second task assignment information about tasks in one or more other scheduling classes and assigned to the processor cores, and refers to the first task assignment information and the second task assignment information to assign a runnable task in the first scheduling class to one of the processor cores. Prior to the assigning the runnable task, the runnable task has been assigned to one of the processor cores.

Abstract: A computing system with multiple processor cores manages power and performance by dynamic frequency scaling. The system detects a condition when a total number of active processor cores within one or more clusters is less than a predetermined number, and an operating frequency of the active processor cores has risen to a specified highest frequency. The system also obtains ambient temperature measurement of the one or more clusters. Upon detecting the condition, the system increases the operating frequency above the specified highest frequency based on the ambient temperature measurement while maintaining a same level of supply voltage to the active processor cores.

Abstract translation: 具有多个处理器内核的计算系统通过动态频率缩放来管理功耗和性能。 当一个或多个集群内的活动处理器核心总数小于预定数量时，系统检测到状态，并且活动处理器核心的工作频率已经升高到指定的最高频率。 该系统还获得一个或多个簇的环境温度测量。 在检测到状况时，系统会根据环境温度测量值将工作频率提高到高于规定的最高频率，同时保持与主动处理器内核相同的电源电压。
