Research And Application Of Unified Modeling Language In The Development Of Embedded Software

With the development and changes of computer industry, the research on embedded system is becoming a popular field now. From initial singlechip structure to nowadays embedded structure with special operating system, the complexity and scale of embedded system is growing and extending. Consequently, how to design the complex embedded system is becoming an important task that needs to be discussed now. However, the traditional analysis and design way of embedded system has no unified standards, which makes the system unsatisfying in costs and efficiency , so it is urgent to explore a new way to develop embedded software .As the standard of object oriented modeling technique, UML is suitable for making the design of complex system simplify. It adopts the way of object graphics oriented to describe the system, and it supports the whole process of analysis,design and modeling. As to the analysis and design for embedded system, UML has its special advantages. Through the research of the current technology of UML, combining with the existing problems in the design of embedded software, this thesis presents a solution based on UML to develop the embedded system, and applies it to a system instance.The thesis first introduces some basic knowledge about UML, and then analyzes the main thought and process of software modeling based on UML. It points out the advantages of using UML in the design of embedded system. Meanwhile it proposes the method and environment that based on UML for the development of embedded software. This thesis emphasizes how to use UML to specify and design embedded system. Simultaneously, according to every phase of modeling process and with the guidance of the method proposed in this paper , we design an embedded fingerprint door monitor system. The thesis gives the whole process of how to use UML to design this system, and it discusses the key techniques in the modeling process. In additional, on the basis of the research on the mechanism for the verification of embedded system...
