Abstract

The invention relates to the field of processors and provides a scheduling method, device and system for a processor. Central processing units (CPUs) comprise at least one first CPU and at least one second CPU. Every first CPU comprises a first processor inner core and a second processor inner core, and every second CPU only comprises the first processor inner core. Application programs are marked with category labels, the category labels mark that the application programs are high or low in operation performance requirements; the category labels of the to-be-run application programs are obtained in the system operation process; and the to-be-run application programs are distributed to be processed through the first CPUs or the second CPUs according to the category labels of the to-be-run application programs and categories of the CPUs. According to the scheduling method, device and system for the processor, system resources are saved, and cooperative work of software and hardware is achieved reasonably.

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. ) power consumption and launched the "big.LITTLE technology". 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 Cor...
