| 摘 要： | 针对实时应用接口（RTAI）的调度器是基于静态优先级调度，不支持动态调度的缺点，提出将单调速率调度算法（RM）和最小空闲时间优先调度算法（LLF）引入到RTAI调度器中，实现了静态优先级结合动态优先级调度的调度模型，扩展了RTAI调度器的实时性。最后对扩展调度器进行测试，验证了这种扩展策略是正确的。

| Abstract: | Because Real-Time Application Interface(RTAI) scheduler is based on static priority scheduling and not compatible with the dynamic scheduling,this paper introduces Rate Monotonic Scheduling(RM) and Least Laxity First Scheduling(LLF) to RTAI Scheduler,expanding the real-time of the RTAI scheduler,and getting a scheduling model by combinating of the static priority scheduling and dynamic priority.Finally,the article demonstrates the test of the expansion of scheduler to verify the validity of this expansion s... |
