Dynamically Interchangeable Framework for Component Behavior of Embedded Component Systems

The development of information technology and the improved performance of embedded devices have led to embedded software of increasing scale and complexity. Component-Based Development (CBD), which divides software into components and subsystems, is effective for efficiently developing large-scale embedded software. However, components created in CBD are not interchangeable dynamically while the application is running, and components written in C must be compiled to change and run. To address this issue, this paper proposes the component framework using mruby to change the component behavior dynamically. The proposed framework works on TOPPERS Embedded Component System written in C. Experimental results show that the time it takes to change the behavior of the component is shorter using the proposed framework than using a component written in C. The proposed framework can realize CBD more efficiently.
