Real time multitasking design with a graphical tool

Abstract

LACATRE is a graphical language intended to help in design for applications requiring multitasking real time executives. Within the software life cycle, it is used for both preliminary and detailed design. The paper presents new high level objects destined to facilitate the link between commonly used methods for specification and design and the detailed design using multitasking executives. The paper describes ideas concerning the use of such a tool in the frame of education, and industry in the case of medium size applications where developers have a lack of tools.<>
