The testing of timing performance for a real-time embedded operating system

rapidly explore the design space of a real-time embedded system, It is essential to be able to efficiently analyze the timing behaviors of different system architectures. Unfortunately, understanding the exact timing behavior of an embedded system can be computationally prohibitive. Previous work in this area has mostly focused on producing a yes/no answer to the schedulability of system architecture under the worst-case scenario. This not only often leads to overly pessimistic designs, but also provides no insight as how to rank different architectural designs with respect to their timing performance. In this paper, a superior metric has been identified and used to effectively measure the timing performance of a design.
