To solve the software complexity and maintainability problems, component-based software development is widely adopted in various fields. A component framework for μITRON OS named TECS is a kind of static component system. On the other hand, RT-Component framework that has been developed is a kind of dynamic component system. Static component frameworks are suitable for low level software layer that requires real-time capability, safety and reliable quality. In this paper, we propose three architecture to integrate TECS components and RT-Components, and their advantages and disadvantages are discussed.
