Abstract :
This paper presents performance results of the object-oriented real-time operating system Theta. There are two current versions of Theta which are written in the object-oriented languages, C++ and COB. In both languages, object-orientation is embedded into the C language. The overhead of the C++ and the COB versions are compared with that of C. Our experiments show that if the classes are carefilly chosen, there is no significant overhead for real-time applications.
