Abstract: In hard real-time multi-tasking systems each task has to meet its deadline under any circumstances. If one or several tasks violate their timing constraints, compiler optimizations can be used to optimize the Worst-Case Execution Time (WCET) of each task with a focus on the system's schedulability. Existing approaches are limited to single-tasking or strictly periodic multi-tasking systems. We propose a compiler optimization to perform a schedulability-aware static instruction Scratchpad Allocation for arbitrary activation patterns and deadlines. The approach is based on Integer-Linear Programming and is evaluated for the Infineon TriCore TC1796 microcontroller.
