Several real-time protocols have been proposed, for both static and dynamic scheduling approaches in single and multi-core processors. One of the main factors for performance efficiency in such protocols is the way they are implement within a real-time operating system (RTOS). In this paper we present an object-oriented design of real-time access protocols considering single and multi-core systems and also suspension- and spin-based protocols (7 protocols in total). Our design aims at reducing the run-time overhead and increasingcode re-usability. By implementing the proposed design in an RTOS and running the protocols in a modern multi-core processor, we provide an analysis regarding the memory footprint, run-time overhead, and the impact of the overhead into the schedulability analysis of synthetically generated task sets. Our results indicate that proper implementation provides low run-time overhead (up to 6.1 us) and impact on the schedulability of real-time tasks.
