In the scope of this work, we propose a concept for timing annotation and control blocks in C++. Our proposed blocks can be used to measure and profile software block execution timing. Furthermore, it can be used to control and enforce the software timing behavior at run-time. We have implemented our concept in a C++ library and tested it on an ARM Cortex A9 bare-metal platform. The usage of our library has been evaluated on a critical flight-control software for a multi-rotor system. The results show that our concept is working, while still having some room for systematic accuracy testing and optimization.} @COMMENTBibtex file generated on
