Implementing real-time aspects and distribution in an object-oriented language: the DEAL experience

As part of a research project to realize a reliable distributed operating system (DEDOS) with a guaranteed real-time response an object-oriented language, called DEAL (DEDOS Application Language), has been defined to deal with specific aspects most sequential languages do not cover. The language allows the creation of programs for execution on a multiprocessor configuration, with access to services of other programs. The first version of this language is simply an extension of C++. The paper describes implementation issues of the DEAL runtime environment and the preprocessor that translates DEAL programs to C++ programs.<
