Of. Wince.net Pxa255 Processor Transplantation And Application,

Computer is in the era of "post-PC" , the main role is embedded computer system. Embedded system is the special computer system whose center is application, basic is computer technology, and software and hardware is cuttable, and which is suitable for the request of function, credibility , cost, volume, power by application.WinCE. net is one of the embedded RTOS, which not only develops as much as VXworks, Linux, QNX and pSOS, but also is one of the microsoft's stratagem for embedded OS platform.The main special of Embedded OS is that it can run on different platform, WinCE.net has supported the mainstream processor until now. PXA255 is especially suitable for consumer electrics, which is posted by Intel. The platform whose centre is PXA255 is a good environment for wince.net. The main work of the thesis is to port wince. net to such a platform, build a foundation for application.According to the level model of WinCE. net, the writing and integration of BSP (Board Support Package) is the stress of porting WinCE. net. Modifying eboot by hardware, writing the OAL which is connected with hardware, and writing drivers are included. From some point of view, BSP can be treated as a mini-OS, the integration is also one part of the thesis.Building a proper OS based on BSP is also one part of the thesis. To get a system that can run well needs to rectify the configuration of custom OS. Applications are the aim of porting EOS. The program in WinCE.net is different with the one in windows. The thesis implements some practical application on the custom platform , which validates the all-right of the porting work.
