A Framework for Rapid Development of Embedded Real-Time Systems

The development of embedded real-time system has grown to a hot topic in current computer research and application.This paper presents a platform based design methodology for rapid development of embedded real-time system,which incorporates the idea of the platform-independent and platform-specific model of Model Driven Architecture.First,we build a hard real-time operating system platform by using the Embedded Linux Operating System with the Real-Time Application Interface.Then,the model of the real system is created and simulated and the real-time driver model is exploited by using the Matlab/Simulink/Real-Time Workshop combined with RTAI-Lab tools and executable code is automatically generated.Finally,the code is loaded to the embedded real-time system.An embedded real-time controller system for the inverted pendulum is designed,which shows that this methodology can reduce the design complexity of the system effectively and exploit the embedded software with greater efficiency.
