Abstract

Embodiments of the present invention provide a method and device for process scheduling, which are applied to a Linux system. The Linux system includes a secondary scheduling component, and an application program is installed on the Linux system. The method includes: An input instruction of a program; in response to the input instruction, create a process corresponding to the application program; wherein, the process includes a plurality of threads; judge whether the number of the threads exceeds a preset threshold; when the number of the threads exceeds a preset threshold When the threshold is set, the secondary scheduling component is used to schedule the process; one or more exclusive CPUs are set for the secondary scheduling component to ensure that the secondary scheduling component monopolizes one or more CPUs, reducing task switching overhead, thereby maximizing Maximize the improvement of system performance and avoid the huge workload of developing a new operating system. The simple and efficient system including secondary scheduling components has excellent performance and can maximize system efficiency.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a process scheduling method and a process scheduling device. Background technique [0002] In the prior art, embedded development has the following options from the perspective of bottom operating system platform selection: based on open source operating systems, such as Linux, based on commercial operating systems, such as VxWorks, self-developed operating systems, bare metal without operating systems ( Computer bare metal refers to an electronic computer without an operating system and other software) mode. [0003] Solutions based on the open source Linux operating system are very common, but software based on the Linux operating system is generally more complicated, requiring a deep understanding of task scheduling and process / thread models under Linux, which has high requirements for developers, and the Linux operating system The switching and preemption of mu...
