Abstract [en]

The use of component technology in embedded systems brings new challenges to this domain. One important issue is how to derive properties of the system when we know the properties of the system’s components. When the system is real-time, it is useful to find out how component composition will affect the execution time of tasks made out of components. In this work, we use a statistical design to examine and rank different hardware features with respect to their impact on the execution time at component composition. Our results indicate, for example, that main memory latency and the block size of the L2 cache have the greatest effect, while memory bandwidth has the least effect.
