An efficient time annotation technique in abstract RTOS simulations for multiprocessor task migration

Complex control oriented embedded systems with hard real-time constraints require real-time operation system (RTOS) for predictable timing behavior. To support the evaluation of different scheduling strategies and task priorities, we use an abstract RTOS model based on SystemC. In this article, we present an annotation method for time estimation that supports flexible simulation and validation of real-time-constraints for task migration between different target processors without loss of simulation performance and less memory overhead.
