This paper describes an experiment in programming part of an operating system kernel using the Esterel synchronous programming language. Using a synchronous programming language allows the construction of provable, deterministic reactive systems. The paper describes and analyzes the small executive realized and the formal verification of some of its properties. It also presents how multiple interconnected...
High-integrity computer systems are usually required to go through a strict verification and validation process, often leading to certification according to some safety or security standard. Verification activities may include some kind of static analysis because some types of errors cannot be removed just with testing. Temporal analysis techniques are available for systems with hard real-time requirements,...
The paper describes the design and implementation methods used by BAeSEMA to support their development, over the last ten years, of very large Distributed Command and Control Systems written in Ada 83. It describes the characteristics of our Common Framework and the strategy for extensive use of automatic generation of Ada 83 code from a Design Data Base. Over 2.5 million lines of code have successfully...
