碩士 === 東海大學 === 資訊工程與科學系碩士在職專班 === 96 === Abstract Developing an embedded system is a very complicated task, which not only faces the same problems as developing an ordinary system, such as unclear demand, complex systems and difficult maintenance and so on, but also must overcome the time limit and low-power consumption in a real-time system. An important shortcut is increasing the reusability techniques for developers to solve these problems, rapidly develop a new system, and reduce the developing cost. In this thesis, we use the reusability technique of pattern redirection, and propose an idea of pattern for the development of embedded real-time systems, where a pattern is a reusable design to achieve reusability and shorten the development cycle. To meet various needs of embedded system products: rapid development, rapid update, as well as flexibility, modifiability and reusability, this thesis also proposes a general analysis model of embedded real-time systems --- RTESRP (Real Time Embedded System Requirements Pattern) to complete the requirement analysis based on the pattern-based method in software engineering. The model also uses UML (Unified Modeling Language) to describe the requirement analysis, solve the problems with real time, reliability of requirement and so on in requirement analysis, speed up the development, and reduce errors due to incomplete analysis information of embedded systems. Using patterns can not only shorten the time and flow of system development, but also enhance the quality, reduce the maintenance cost, and make the product more competitive. The thesis finally illustrates an instance of patterns with a real application in requirement analysis of embedded real-time systems.
