摘要： A method of processing data using a data processor having an operating system for performing tasks of an application programme, and a power and performance controller controlling parameters and modes of execution of the tasks by the data processor. The power and performance controller includes a performance predictor producing an estimation of required performance of the data processor for the tasks taking account of inactive periods of the tasks and adjusting the performance and power consumption of the data processor in response to the estimation. The performance predictor distinguishes for each of the tasks between: —available inactive periods of the task during which the operating system is available to continue to process the same task, and —unavailable inactive periods of the task during which the operating system is not available to continue to process the same task. A substantial improvement is obtained in quality of service, with fewer missed deadlines in performance of the tasks.
摘要翻译：一种使用具有用于执行应用程序的任务的操作系统的数据处理器处理数据的方法，以及控制数据处理器执行任务的参数和执行模式的电力和性能控制器。功率和性能控制器包括性能预测器，其产生对考虑到任务的非活动时段的任务的数据处理器的所需性能的估计，并且响应于估计调整数据处理器的性能和功耗。性能预测器区分以下任务之间的任何一个任务： - 操作系统可用于继续处理相同任务的任务的可用非活动时段，以及不可用操作系统的任务的不可用非活动时段继续处理同样的任务。在服务质量方面取得了实质性进展，执行任务期限较短。
