PROCESS MODEL FOR EFFICIENT IMPLEMENTATIONS OF GRAPHICAL SPECIFICATIONS IN THE FIELD OF EMBEDDED REAL-TIME SOFTWARE

摘要

The model-based approach in the development of innovative embedded software is becoming more and more important to master the new challenges (e.g. increasing complexity, shorter time to market, continuously evolving hardware, etc.). Nowadays most of the CASE-tools used allow the generation of code for the final implementation of such graphically specified systems. In our opinion the on-way mapping of graphically specified functions onto real-time capable software is not efficient enough to meet all the requirements of the embedded market. So in this contribution we propose a new process-model for the efficient implementation of graphical specifications onto embedded systems. A new analysable software architecture is described. It allows the timing analysis of a dedicated implementation almost automatically giving valuable feedback to the designer after "pushing the code-generation-button". With the suggested realization all the necessary parameters can be gained automatically and integrating the developed mathematical algorithms in the adopted CASE-tool the procedure of performance analysis becomes an easy part within the implementation phase. The tool integration reduces the needed know-how of the developer about the mathematical analysis to the interpretation of the results.
