GRAPHICAL LANGUAGE FOR REAL-TIME MULTITASKING APPLICATIONS DESIGN

LACATRE is a language, with a graphical and a textual mode, devoted to ease both the preliminary and detailed design of applications involving real-time multitask executives. LACATRE makes an intensive use of a graphical symbolism allowing thereby the giving of a synthetic and precise vision of the multitasking applications. This language, with its two modes, can be considered as the basis of a Computer Assisted Software Engineering (CASE) environment devoted to multitasking real time applications, and adaptable to a lot of standard real time executives. In this context, starting from the application graphical drawing, the skeleton of a multitask program for the selected target executive may be obtained.
