摘要： A method of controlling the clock frequency of a processor executing software in a plurality of active periods, the method comprising, for each period: supplying to a power management application at least one parameter defining an execution profile for the period having high frequency and low frequency operating intervals; the power management application determining, based on said profile, granted clock frequencies for the high and low frequency operating intervals; the processor supplying to the power management application at the commencement of a period an operating cycle requirement for the period; the power management application determining, for each period, based on the operating cycle requirement, the length of the low frequency interval; and controlling the clock frequency in each interval based on the granted clock frequencies determined by the power management application.
摘要翻译：一种控制在多个活动期间执行软件的处理器的时钟频率的方法，所述方法包括：对于每个周期：向功率管理应用提供定义具有高频率和低频率的周期的执行简档的至少一个参数操作间隔; 所述功率管理应用基于所述简档确定用于高频和低频操作间隔的时钟频率; 所述处理器在所述期间的操作周期要求的一段期间内向所述电力管理应用提供; 电源管理应用程序根据操作周期要求确定每个周期的低频间隔的长度; 以及基于由电力管理应用确定的授权时钟频率来控制每个间隔中的时钟频率。
