Operational semantics of a kernel of the language ELECTRE. (English) Zbl 0769.68085
Summary: The real-time language ELECTRE describes behaviours of a real-time application using tasks called modules. Tasks are activated and pre- empted by events that come either from tasks themselves or from the controlled real-time application. To describe a current state of the application one needs both a program ELECTRE and the history of past event occurrences. We give operational semantics for a kernel of the language using a transition system whose transitions are calculated by attribute evaluation on a context-free grammar. It proves that any event occurrence turns any state into a new one, in a deterministic way.
