Component-based constructing approach for application specific embedded operating systems

Rapid advances in the real-time embedded operating systems necessitate the development of Internet oriented application specific embedded operating systems. The ASOS (application specific embedded operating systems) has now become a promising research direction of the embedded operating system. The paper clarifies the concept of the ASOS, and takes the embedded operating system applied in the traffic signal controller we are now developing to illustrate the main characteristics of the ASOS. Benefits from the CBSE (component-based software engineering) include system quality improvement, shorter time to market, integration of complex systems, etc. However, as for the embedded system, the component-based technology and theories still in an exploration period, though many projects are carried on. In this paper, we present the process of our approach to construct the ASOS based on the component technology.
