Embedded processors have become increasingly complex, resulting in variable execution behavior and reduced timing predictability. On such processors, safe timing specifications expressed as bounds on the worst-case execution time (WCET) are generally too loose due to conservative assumptions about complex architectural features, timing anomalies and programmatic complexities. Hence, exploiting the latest architectures may not be an option for embedded systems with hard real-time constraints where deadline misses cannot be tolerated.
