Integration Of Embedded Systems And Tools

It is over ten years from research embedded systems analysis and design in our country. Now some methods of embedded systems analysis and design have come into being. Although it has acquired some achievements, it can' t meet needs of people. Now it limits for use of Embedded software development environment, because can' t meet most requirement of users. The only way we must research embedded systems integration and design method, integration embedded software development environment is required also.However, as a kind of important and complicated system software, embedded software development environment is a high-tech, expensive and necessary tool of the modern embedded system. . The ultimate solution-how to build the embedded IDE that can achieve integrated, open and applicability and agility to this day.First, this article dissertate the concept and main character of Embedded systems. Next, discuss formalized analysis, structured analysis and object-oriented analysis. Then, this dissertation presents the primary conceptions of Software Architecture (called SA), and the methods to describe it. Meanwhile the dissertation gives an idea of the component development framework based on SA and middleware. According to the analysis above, the dissertation declares a Toolbus Integrated Mechanism (called TIM) based on Toolbus, a set of tool interfaces and a kind of dynamic and extensible message mechanism which is user-friendly and can update the analysis functions in run time dynamically to refer to the inefficient communication between the components. Additionally, A model including tool component and tool adapter is designed to suit the Toolbus. The structure of TIM is flat, and it is the only way to support the interactions between tools. TIM satisfies the requirement of plug and play, and allows user to replace and update tools. Finally, the article bases on the application requirement, mainly studies the theory and technology related to the integration of different software requirement analysis approaches, and offers the integrated scheme of the integrated meta-model approach, the approach can make the requirement information expressed by two analysis approaches become the united expression, it can come into being a new requirement model.
