System response time is a key element in hard real systems. In classical Real Time Operating Systems (RTOS) based on software schedulers, overhead and jitter are major problem when the number of tasks rate context switches high. Increased values for those parameters over admissible can lead to performance degradation, increased power consumption or even deadline misses. If part scheduling components entire functionality moved from hardware, significant improvement task switching times be...
