Abstract
(EN) A method for allocating computational resources of a processor, comprising: detecting current processor load (S102); determining required computational resources according to the processor load, the computational resources comprising a sum of frequency values of each processor core (S104); obtaining power values of prior processor cores at particular frequency values, and determining the number of processor cores and the frequency value of each processor core according to the power values of the prior processor cores at the particular frequency values, so that the sum of the frequency values of each processor core accords with the computational resources and the sum of the power values of each processor core is minimum (S106). By means of the method, the power consumption of a terminal can be reduced.
(FR) La présente invention concerne un procédé d'attribution de ressources de calcul d'un processeur qui consiste : à détecter une charge de processeur actuelle (S102) ; à déterminer les ressources de calcul requises en fonction de la charge de processeur, les ressources de calcul comprenant une somme de valeurs de fréquence de chaque cœur de processeur (S104) ; à obtenir des valeurs de puissance de cœurs de processeur antérieurs à des valeurs de fréquence particulières, et à déterminer le nombre de cœurs de processeur et la valeur de fréquence de chaque cœur de processeur en fonction des valeurs de puissance des cœurs de processeur antérieurs aux valeurs de fréquence particulières, de sorte que la somme des valeurs de fréquence de chaque cœur de processeur correspond aux ressources de calcul et que la somme des valeurs de puissance de chaque cœur de processeur est minimale (S106). Le procédé permet de réduire la consommation d'énergie d'un terminal.
(ZH) 一种处理器计算资源的分配方法,包括:检测当前的处理器负载(S102);根据所述处理器负载确定所需的计算资源,所述计算资源包括每个处理器核心的频率值之和(S104);获取先验的处理器核心在特定频率值的功率值,根据所述先验的处理器核心在特定频率值的功率值确定处理器核心的数量以及每个处理器核心的频率值,使得每个处理器核心的频率值之和符合所述计算资源,且使得所述每个处理器核心的功率值之和最小(S106)。采用该方法,可降低终端的功耗。
