RTOS kernel performance evaluation technology research based on loads of task and interrupt

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.
