μC／OS III的中断响应时间分析测量与改善

摘要

在特定的平台下，测量了μC／OS III的中断响应时间，分析了临界区对μC／OS III中断响应时间的影响，并提出了改善μC／OS III实时性的方法。实验结果证明，在系统设计不太复杂的情况下，μC／OS III的中断响应时间可以控制在4μs以内。%In a specific platform ,the interrupt response time of μC/OS‐III is measured and the critical region effect on interrupt response time is analyzed .Finally ,the method of improving the real‐time property of μC/OS‐III is proposed .The experiment results show that the interrupt response time of μC/OS‐III can be controlled under 4 μs .
