Research For The Et-Lotos-Based Embedded Software Component Composition

CBSE (Component-Based software Engineer) is one new approach among the several development approaches for embedded software. Based on the features of the embedded software, it effectively reduces the complication, supports the concurrent development and makes reuse more efficiency and brings down the development cost. The technology of component composition is the core of the component-based development as well as the focus of this paper. Grounded on the model of embedded software component and software architecture (SA) described by the ET-LOTOS (a formal software architecture description language), this paper discussed both component composition and the non-functional requirements, and then proposed templates of the composition connection and an algorithm for composition.
