摘要
实际开发实时多任务操作系统时,划分任务的好坏和优先级的设置直接影响到系统性能的好坏和执行效率的高低。通过利用实时操作系统开发嵌入式多任务系统软件,先将系统功能合理划分,构造不同的任务,并根据任务的重要性设置其优先级。任务划分和任务优先级在电解质分析仪系统中的应用,不仅减少了开发工作的负担,而且使系统主CPU的资源得到了充分利用,使得该系统的功能结构更加人性化。
In developing a real-time operating system, task division and priority setting can directly affect the system performance and the execution efficiency. The task should be rationally divided in the development of a multitask system software based on the rea[-time operation system and the priority should be set on the basis of the importance of the task. Task division and task priority were applied to the electrolyte analyzer system, which not only reduced the development work burden, but made the most use of the CPU resources of the system and made the system even more user-friendly.
