Industry-oriented Applications Embedded Programming Middleware Research

The developing of computer, communication and network technology makes the information technology(IT) to spread into all aspects of the society. The embedded computer technology is developing with the shorts of develop software in during the IT development. With the aim of developing a large of embedded computer equipments, we need more quickly and easier design large number of software. Then, we can design a kind of embedded middleware that can shield the different of the Operating Systems (OS) application program interfaces(API). The middleware can supply uniform APIs to the applications.Because of the difference of operating systems, the applications need be designed servial times. In order to resolve the problem of applications migrate on different embedded operating systems, we use the embedded middleware between the application and the Operating System. First, the paper introduce several middleware products that have been devised by famous organizes; then, we introduce some methods to design the middlewares. The migrate middleware in different embedded OSs designed by reference virtual files system(VFS) of Linux is first designed in the paper.In the paper, we have designed an Operating System Extension(OSE) and Oriented-entironment detect Extension of Embedded Operating System. The OSE is designed for"the tenth five-years plan", supply some extension function that need by the engine. We design a demo to display the function of the OSE in the paper. The paper also test and analyze the time consume of the OSE.The Oriented-entironment detect Extension is designed as a standard APIs of entironment detect field. The APIs has two parts that are system APIs encapsulation part and function extension part. The system APIs encapsulation part is base on the operating system APIs; the function extension part is designed for special function supply for the entironment detect. We also realize several APIs that devise for the special function in paper.
