The Design And Driver Exploitation Of Automobile Multimedia System Based On Windows CE

With the development of automobile market in china and the rising of value content of automobile electronic, the automobile electronic industry will form a enormity scale of ecnomy in china.At present, the automobile industry of china is faced with huge impact.The development of automobile electronic is the urgent affair.The project is supported by science development program in Tianjin. The system chooses a design method of embedded system. This paper carried out research in these aspects as follows:Firstly, on the basis of reseach on the design methods of embedded system, this paper presents holistic design of the system. According to the design method of embedded system, the software and hardware are made certain. The hardware frame of this system and the develop steps are given.Secondly, after analyzing the operating system-Windows CE deeply, this paper presented the development process of transplanting Windows CE to ARM, the microprocessor. It included BSP customed, system customed and OAL customed. On this basis, this paper put forward a modular design method, that was, managed and desinged the three transplanted parts modularly. This made the design clear, and what's more, it enabled the transplant of operating system much more universal.Thirdly, on the basis of analyzing the driver model in Windows CE, this paper completed touchscreen driver that was based on ARM in the hierarchical driver structure. This structure is propitious to transplant program, thus can shorten development cycle and easy to maintaine.And then this paper completed serial driver and SD card driver in the structure of streaming interface driver.This automobile multimedia system obtained expectant result by practical running, fulfilled the design's purpose. Sum-up of this paper's main work was made, at last. The paper also described the prospect of the automobile multimedia system.
