摘要：
It is difficult to compare real-time operating systems. To make a comparison, information is required about the performance and determinism of the real-time operating system being examined. Of great interest is the maximum latency time of the operating system itself. Therefore it is necessary to clarify which latency times exist, and how they arise. This paper introduces a new measurement method which helps to collect sufficient information to determine the system behaviour for the worst-case scenario. Finally the paper takes a closer look at some of the measurement data obtained using this new method.
