| Abstract: | Real-Time application environmen t requires that the system behavior of RTOS must be predictable.This paper syste matically analyses the Real-Time performance items which should be tested an d measured in order to evaluate a RTOS.This paper also gives two methods of ge tting the absolute time reference,which is needed to measure time intervals, and analyses the parameters which will impact the system responding time.Finall y,as an example,this paper shows the steps to measure the thread switch laten cy of ARTSOS. |
