Embedded Driver Design And Implementation

With the rapid development of the computer network technology and the electronic technology, the world is stepping into post-PC era, during which people gradually know and accept a new concept, embedded system. Unconsciously, many kinds of embedded digital products have become the main tools of processing information after PC. At the same time, the life of people is closely linked with Internet so that it is natural for the embedded system to connect to Internet.The device driver of embedded system must be customed and be one part of embedded operation system and applications not to be separate. So every embedded device must design the special device driver in development. There are many example of drivers have been provided with embedded operation system, but every one of it must be modified to fit the hardware environment, enven to redesigned.In this paper, we introduced how to design the proper embedded device drivers on the specail embedded operation system, we analysed the the interface-design and data-struct of the drivers, discussed the design-principle of some important modules, and offered some suggestion for the problems in developement.
