| The application of the embedded system has already got deeply to many respects of the people's lives; it has played a very important role for improving the life quality of the people. In this case, the productivity and quality of the embedded software become more and more important. Software reuse is the feasable approach to improve software quality as well as software productivity, and component technology, which is considered one of the cores of software reuse, has already been gradually applied to traditional software development. Therefore, it avoids duplication of work and greatly enhances the efficiency of software development.This paper analyzes software reuse, component technology and software architecture, and then on this basis, takes into account the basic characteristics of the embedded system, and combines with the function of the centric server of the digital home, studies the application of the component technology in the that system. At the same time, this paper summarizes the existing component model and the component-based embedded software development; it presents a domain-oriented component model, which is suitable for the service center of the digital home. The model has good features, such as configurable, scalable, portable, self-adaptability and it is easy to implement. It is also a feasible solution to the development of cable-based broadband network for the service center of the digital home.In addition, the intelligent component container provides a special function that dynamic replacement and update, in order to meet the growing demand for new business in the service center of the digital home. At the same time, its open architecture, allows it easy to expand, which makes it easily adapt to the changeable business in the future.Finally, with the advantage of school-enterprise cooperation, the component model is applied to the service center of the digital home, and it is also promoted and improved. |
