DEAL: an object-oriented language for distributed real-time systems

This paper describes the language-design rationale and the most interesting features of a programming language for distributed real-time systems. The language, called DEAL, is object oriented and based on the C++ language. To make DEAL suitable for the implementation of hard real-time applications there are some restrictions as well as extensions to the C++ base-language. The most prominent language extensions are those pertaining to concurrency and the specification of timing properties of objects.
