MULTI-PARADIGM METHODOLOGY AND TOOL FOR REAL-TIME EMBEDDED CONTROL SOFTWARE DEVELOPMENT

摘要

This paper presents a multi-paradigm methodology andrntool for Embedded Control Software (ECS) design. Thisrnmethodology is based on model-driven development, it definesrna common metamodel that unifies the ECS designrnphases and ensures the consistency of models along the designrncycle. The methodology uses two software paradigms:rnin one side, the software component paradigm that increasesrnmodels reusability to face the increasing complexityrnof ECS; in the other side, the aspect-oriented paradigmrnthat allows to model transversal real time properties andrnsupport models analysis and validation in the earliest stepsrnof the ECS design cycle. A tool called MoDEST implementsrnthis methodology and enables real-time schedulingrnanalysis/simulation and an automatic real-time code generation.rnIt should help designers to choose the best schedulingrnthat preserves the control performance and quality ofrnthe designed ECS.
