Toward An Incremental Development For Real Time And Embedded Systems

This paper presents a new methodology to development complex embedded systems for hard real-time applications, based on incremental model in order to make the latter compatible with the particularities of embedded systems. In this paper, we first introduce the methodology proposed and describe it step by step, based on SART((Structured Analysis Real-Time) and MARTE (Modeling and Analysis of Real Time and Embedded Systems) profile for analysis and modeling of real-time systems. The suggested methodology is illustrate with a two case studies for development of hydrostatic bearing lubrication system and triaxial appartus system.
