Abstract

The invention relates to the field of processors, and provides a processor scheduling method, device and system. The CPU includes at least one first-type CPU and at least one second-type CPU, the first-type CPU includes a first-type processor core and a second-type processor core, and the second-type CPU only includes a first-type CPU A type of processor core; the application program is marked with a category label, and the category label indicates that the application program is an application program with high running performance requirements, or an application program with low running performance requirements; The category label of the application program; according to the category label of the application program to be run and the category of the CPU, assign the application program to be run to be processed by the first type of CPU or the second type of CPU. The invention saves system resources and reasonably realizes the cooperative work of software and hardware.

Description

technical field [0001] The present invention relates to the field of processors, in particular, to a processor scheduling method, device and system. Background technique [0002] With the increasing popularity of the Android system, there are more and more Android applications in smartphones and tablet terminals, and the requirements for system performance and power consumption are also getting higher and higher. Introduced "big.LITTLE Technology" for power consumption. This technology uses CPU core groups (clusters) with different microarchitectures according to the processing load of the terminal, thereby achieving both low power consumption and high performance. [0003] In principle, as long as the CPU cores with the same instruction set architecture can apply big.LITTLE technology, currently the combination of Cortex-A15 and Cortex-A7 can be used. Combining the processing performance of the ARM Cortex-A15 MPCore™ processor with the energy-saving effect of the Cortex-A...
