Abstract
The major difficulties encountered by those who have to solve Industrial Real Time Applications, in a multitask computing environment, are:
-
the expression of the dynamic aspect of this type of applications,
-
the number and the variety of these Real Time Executives.
An answer is given to the second problem by the Standardisation efforts, now performed by Real Time Executive constructors in order to promote Real Time Executive standards.
In order to take both problems into account and to bring up global answers, we define the LACATRE language (LAngage de Conception d’Applications Temps REel) which allows the modelling of an application using graphical representations of the main entities handled in commonly used Real Time Executives.
LACATRE is a language, with a graphical and a textual mode, devoted to facilitate both the Preliminary and Detailed Design of applications involving real time multitask executives. LACATRE uses intensively a graphical symbolism allowing a synthetic and precise vision of multitask applications. It allows the expression of the dynamic decomposition and task relationships, in order to obtain the skeleton of the multitask program but not a precise description of the computation.
