Embedded real-time system modeling language analysis and comparison

Auto cruise control system (CCS) is a typical case of embedded real-time systems (RTES). Model-based design method describes both system software and hardware structure by the effective modeling language in RTES. That satisfies RTES real-time capability and reliability, and enhances productivity and saves cost expenses. This paper models CCS using the modeling languages UML (Unified Modeling Language) and AADL (Architecture Analysis and Design Language) respectively, and analyzes the characteristics of the two languages, then discusses RTES modeling development trend.
