Abstract :
To understand the behaviour of a hard real-time embedded system in the presence of highly nondeterministic architectural features requires empirical measurement and analysis of task execution times. This study compares noninvasive measurement techniques with invasive software instrumentation. It shows through experimentation that low overhead measurement functions introduce just over 0.005 percent error, indicating that invasive techniques can reliably measure task execution time whilst achieving highly desirable platform independence
