In the paper,a multi-core embedded scheduling method based on core set is proposed.This method adds core set attributes to tasks.When the scheduler selects successor tasks,it needs to meet high priority requirements.The current core belongs to the task core set with two conditions.The scheduling method proposed in this paper can specify core set attributes for tasks,and limit the task to run on the specified core set.Compared with the original scheduling method that can only bind one core or all cores,the method proposed in this paper is more flexible,and the operating system core load more balanced.
