Abstract
The complexity of hardware and software architectures used in today's
embedded systems make a hierarchical, composable timing analysis
impossible. This paper describes the source of this complexity in
terms of mechanisms and side effects that determine variations in the
timing of single tasks and entire applications. Based on these
observations, the paper proposes strategies to reduce the complexity.
It shows the positive effects of these strategies on the timing of
tasks and on WCET analysis.
