Title
(EN) Method and apparatus for allocating computing resources of processor
Abstract
(EN)

A method for allocating computing resources of a processor is provided. The method includes the following. A current processor load is detected. Required computing resources are determined according to the current processor load. The required computing resources correspond to a total frequency of each processor core. The minimum number of required processor cores is determined. The maximum number of the processor cores in a system is obtained, and a selectable range of the number of processor cores is determined. A plurality of frequency allocation strategies are obtained according to a formula Nc_x*Fx=Nc_min*Fmax. A correspondence between operating frequencies and power values of each processor core is obtained, and a frequency allocation strategy is determined, such that a total frequency of each processor core satisfying the computing resources and a total power value of each processor core is minimum.
