Abstract
Due to real-time systems' good real-time., predictability, scalability and high reliability, they are widely used in aerospace and medical fields, etc. VxWorks is an important realtime operating system. In order to fully test the real-time performance, this paper deeply analyzes the influencing factors of five key performance indicators such as task switching time, preemption time, interrupt latency time, message communication time and semaphore shuffling time. Based on these, a high precision system clock is used to insert timestamps at the entrances and exits of corresponding operations of each indicator and dynamically test the index parameters. According to the above test method, VxWorks6.8.3 real-time operating system performance is tested. The test results show that the real-time performance of VxWorks6.8.3 is strong, and it meets engineering's performance requirements.
