Design And Application Of Embedded System Based On Processor Intel(?) PXA255

The definition of Embedded System is: A specialized computer system based on application and computer technology, of which the software and hardware can be adjusted to adapt the rigid demand of application system such as function, reliability, cost, size, power consumption etc.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. ARM is the industry's leading provider of 32-bit embedded RISC microprocessors with almost 75% of the market. 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.This paper chose the embedded processor pxa255 of Intel corp. as CPU, how to design a perfect embedded development board based on pxa255 is 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 Xsale. Through the research of the function of pxa255 of Intel corp. we developed an embedded development board. It is proved that the development board has advantage of powerful function and expansibility;2. Through the research of character and migration of the Windows CE.net of Microsoft Corp. we discussed the 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 bootloader, OAL and Device Driver of our development board;3. Through the research of linux, we implemented the migration of embedded linux to target hardware platform.discussed the principle of u-boot and its application in bootloader development;4. Given some application examples of our development board;The product of this paper can easily be applied in other embedded Product development with less change;...
