Execution of a High Level Real-Time Language
MetadataShow full item record
Prototype System Description Language (PSDL) 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 is designed 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. In this paper we describe and illustrate our research results: 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. The required software tools for automated translation and scheduling are also discussed. These tools have been designed and an prototype version has been partially implemented.
