The Research And Application Of Credible Embedded Component

With the rapid development of embedded systems in recent years, embeddedsystems gradually evolved a pillar of cloud computing and networking industry. Asthe soul of the system, especially in large complex systems, embedded softwaredevelopment has become the core of the embedded field competition. However, thedifficulties and bottlenecks encountered for different industry applications, embeddeddevelopment work more and more obvious, embedded applications are becomingincreasingly diverse, especially in the medical, aerospace, automotive, electronics,electric power and energy industry, how to provide more efficient solutions ofindustry and the services of best practices has become the problem that the developerof an embedded software engineering and development need to resolve urgently.Component-based software development (Component-Based SoftwareDevelopment CBSD) technology has matured, the method in the traditional softwaredevelopment has been widely used. Its advantages is to improve softwaredevelopment efficiency, reduce the cost of software development, security the cardquality and flexibility of the component. CBSD method of introduction of embeddedsoftware development will be well to meet the diversity of characteristics of theembedded space and the development efficiency and software quality requirements,and meet the embedded domain knowledge reuse. At present, embedded componentmodel, or a lack of versatility, or the lack of credible protection, or lack ofnon-functional properties of statements, there more or less are some problems.Thesis in the context of the study, through analysis of the CBSD technology,research common component model, according to the embedded software, thephysical, real-time, resource-constrained nature, territorial distribution, diversity, andhardware related features, combined with The current study, an embedded componentthe model DTESD component model.The DTESD component model do analysis and research of the relevant defects ofthe existing embedded component model, and Make relevant solutions. DTESDcomponent not only has the characteristics of the common elements, but also has thespecific features of the embedded components, such as physical, diversity, etc.. Thedetailed description of the various elements of the DTESD component model aredescribed in this article, and design a Systematic description syntax of the element; take into account the diversity of characteristics of the system, particularly theintroduction of the principle of variability; embedded component models for thecurrent are lack of the description of Non-functional attributes as well as qualityassurance, so we are specifically to do credible research, and placed in the propertieselement of component model; In order to better analyze, combined with algebraicthinking, presents the mathematical description of the DTESD components; At the lastpart, a DTESD model application example is bring up, and the actual analysis resultsare given to verify the effectiveness of the model...
