Abstract: In hard real-time multitasking systems, applying WCET-oriented code optimizations to individual tasks may not lead to optimal results with regard to the system's schedulability. We propose an approach based on Integer-Linear Programming which is able to perform schedulability aware code optimizations for periodic task sets with fixed priorities. We evaluate our approach by using a static instruction SPM optimization for the Infineon TriCore microcontroller.
