Embedded Components, Research, And Its Real-time Scheduling Policy

The development of embedded-system application is becoming more and more popular in computer industry。Embedded-system for vehicle fields is more and more popular。Among many development tools, development platform has its advantages in rapid, efficient and low-cost development and helps to improve efficiency and quality of embedded system development。But how to construct an embedded development platform that can support various hardware platforms, meet complication development for different kinds of information products and integrate with exist tools and software is a very difficult problem at all times。This dissertation is devoted to this subject with deep research and practice focusing on software component。Software bus is an advanced software architecture design style now。Just as industry production has been out of burden which led to bus-structure's rise because of the complication of hardware system, software development also has stepped to the"bus age"。The theory of software bus is studied and analyzed component based software engineering。The notion of component and component based development process are discussed as well that the basic requirement of component based software development is discussed。Based on the deep study of general component model and current embedded component model, we research and design a new kind of embedded component model– Inter-process Communication Component Model(ICCM) in which we introduces a new design method that break through the limitation of traditional component model, provides a feasible approach for reusing commercial components and moving them in different environment, and give a new solution for software plug and play。We elaborate the design principle of ICCM, give the architectural and functional model of it in the dissertation。Subsequently,analyze the advantages and disadvantages of it by contrasting with other embedded component model。The real time demand of embedded system is analyzed, and some representative real-time schedule scheme and some classical schedule algorithm are discussed and the importance of real-time schedule for component based embedded system is...
