The Research And Application Of Embedded System For Vehicle Based On Processor PXA255

With the development of communication technology and computer technology, The study of hardware and software of Embedded system based on high speed CPU are also fully developed, Embedded system is widely applied in industry, national defense, medical treatment, communication and so on. Meanwhile, a lot of embedded applications are calling for better performance and functionality of embedded systems.ARM is the industry's leading provider of 32-bit embedded RISC microprocessors. ARM offers a wide range of processor cores based on a common architecture and delivering high performance together with low power consumption and system cost, high performance and specific Thumb instrument set. This paper choose the embedded processor PXA255 of Intel corp.. as CPU, how to design a perfect embedded development board based on PXA255 , then to build a perfect embedded system for vehicle is the most important task of this paper.We summarize our work as follows:(1) We discussed the character and application field of embedded system, the character of ARM and XScale. Through the research of the function of PXA255 of Intel corp.. We developed an embedded development board, and described the detailed design of hardware principle and PCB.(2) Through the research of character and migration of the Windows CE.net of Microsoft Corp..We discussed the detailed way to migrate Windows CE.net to a new hardware platform.And we also migrate Windows CE.net to our development board, sloved the problem of how to develop Boot Loader and Device Driver of our development board.Then we provided two examples, how to developed the Device Driver of LCD and touch screen.
