Abstract: A method and an apparatus for managing and scheduling tasks in a many-core system are presented. The method improves process management efficiency in the many-core system. The method includes, when a process needs to be added to a task linked list, adding a process descriptor pointer of the process to a task descriptor entry corresponding to the process, and adding the task descriptor entry to the task linked list; if a process needs to be deleted, finding a task descriptor entry corresponding to the process, and removing the task descriptor entry from the task linked list; and when a processor core needs to run a new task, removing an available priority index register with a highest priority from a queue of the priority index register.

Abstract translation: 提出了一种用于在多核系统中管理和调度任务的方法和装置。 该方法提高了多核系统中的流程管理效率。 该方法包括当需要将过程添加到任务链接列表时，将该进程的进程描述符指针添加到与进程对应的任务描述符条目中，并将任务描述符条目添加到任务链表中; 如果需要删除进程，则找到与进程对应的任务描述符条目，并从任务链表中移除任务描述符条目; 并且当处理器核心需要运行新任务时，从优先级索引寄存器的队列中移除具有最高优先级的可用优先级索引寄存器。
