| Abstract: | Time performance is a very important parameter in airborne embedded real-time operating system.To evaluate the real-time performance of airborne embedded real-time operating system supporting partitions,this paper analyses the key factors affecting time performance of airborne embedded real-time operating system supporting partitions-error response time,inter-partition data exchange time,process switch time,and partition switch time,gives a method of design and implementation of time performance measurements,and the methods of how to select test points and to eliminate the interfere factors. |
