A Novel Testing Method for Interrupt Response Time

Abstract— Interrupt response time is an important index to measure the real-time performance of real-time operating system. Accurate test data can be the evaluation index for selecting real-time operating system. This paper proposes a test method for interrupt response time based on W2 chip. It can test the statistical distribution of interrupt response time quickly and accurately. The results show that the Linux real-time preempttion patch has better real-time performance than Linux and the two operating systems have better real-time performance under no load. The results also prove that the test method is effective. The test method provides a basis for the development of real-time tasks.

Index Terms— interrupt response time,test method, real time performance,Linux
