Application objects and modularity in real time graphical modelling

Abstract

LACATRE is a graphical language intended to help in the design of applications requiring the use of multitasking real time executives. Within the software life cycle, LACATRE covers both preliminary and detailed design. After a brief description of the LACATRE basic objects, this paper presents the use of the application objects (or high level objects) such as agency and process, associated to the import/export features. These components allow modularity and a structured design of real time applications and promote the creation of process libraries. Thus, it increases programme reusability.<>
