RTX51 Tiny performs cooperative task switching (each tasks calls an operating system routine) and round-robin task switching (each task runs for a fixed amount of time before the operating system switches to the next task). Preemptive task switching and task priorities are not supported. If your application requires preemptive task switching you must use the RTX51 Full Real-Time Executive.
请哪位师兄帮我翻译一下粗体的英文，翻译不准啊，不知道什么意思！谢谢！
