Abstract

The invention discloses a task scheduling method and a task scheduling device for an operating system and a computer, wherein the method includes: triggering and scheduling a task of the operating system through switching of task states; obtaining link index corresponding to the task in a task index table according to priority of the task; and updating positions of the task in a ready task chain table according to the link index. By means of the task scheduling method and the task scheduling device for the operating system and the computer, the task scheduling method which is easy, flexible and efficient can be achieved, and working efficiency of task scheduling for the operating system is improved.

Description

technical field [0001] The present invention relates to an embedded real-time operating system, in particular to an operating system task scheduling method, device and computer. Background technique [0002] Embedded real-time operating system is a system that can complete system functions within a certain time and respond to internal and external events in time. [0003] Task scheduling is one of the core functions of the operating system. Its main function is to select a ready task according to a certain criterion, and jump into this task for execution. The scheduler is the module that completes the task scheduling function. Most embedded real-time operating systems schedule based on priority. Specifically, the operating system assigns a priority to each task, and the scheduler selects the task with the highest priority to execute from the ready tasks. [0004] At present, the implementation methods of the embedded real-time operating system scheduler mostly refer to or ...
