Execution of a high level real-time language

Prototype system description language is a high-level real-time language with special features for hard real-time system specification and design. It can be used to firm up requirements through execution of its software prototypes. The language design is based on a real-time model merging data and control flow, and its implementation is beyond conventional compiler technology because of the need to meet real-time constraints. A special scheme used to meet the hard real-time constraints and the guidelines used to implement such a language in the target language Ada are described and illustrated. The required software tools for automated translation and scheduling are also discussed. These tools have been designed, and a prototype version has been partially implemented
