摘要: 针对现有实时操作系统Benchmark在任务及中断混合负载下的评估“失真”问题,从RTOS内核中断响应模型分析入手,提出一种面向任务及中断混合负载环境下的内核性能评估方法,并以Rhealstone和ThreadMetric两种典型的Benchmark为基础实验平台进行改造与修正,通过对VxWorks、RTEMS、uC/OSII等系统的性能评测,实验结果表明,该评估方法对任务及中断混合负载下的RTOS内核性能评估更具合理性。

Abstract: In order to improve the RTOS’s performance evaluation more accurately in the environment of both task and interrupt, the paper presents an interrupt response based model from the view of RTOS kernel. The evaluation on two typical Benchmark systems, namely Rhealstone and ThreadMetric, with three RTOSs including VxWorks, RTEMS and uC/OSII, shows that the new model can really obtain the more accurate evaluation under the circumstances of mixed load.
