The Research And Application Of Embedded System Based On ARM & μClinux

With the development of the computer, network and communication technology,the embedded system become a new technical focus and orientation in IT fieldfollowing the step of computer and network technology. The thesis lays stress on the research and application of embedded system basedon ARM processor and μClinux operation system. Firstly, the hardware core of embedded system and software core, namely,embedded processor and embedded operation system are depicted generally. Next, inrespect of architecture, instruction set, programming mode and the extension of ARMprocessor are analyzed in detail, and also the selection guide of ARM processor isgiven. As the core of embedded software, μClinux is selected as the embeddedoperation system in this project, in respect of key technical problem of the port basedon ARM processor and the source architecture, function, memory management,process analysis, the solution of real-time and minimization of μClinux core, thethesis provide the detailed analysis. Secondly, based on detailed analysis of ARM processor and μClinux, thehardware and software design scheme of embedded development system arecompleted independently. As for hardware design, the detailed construction andfunction description of every hardware component are given. As for the softwaredesign, the tailored method, configuration and compilation of standard μClinux aredescribed in detail. The hardware and software design of embedded developmentsystem based on ARM processor and μClinux are completed eventually. Finally, the embedded application, GPS communication terminal are given basedon the above development system. The integration of GPS and GSM Modem modeland application software based on the above embedded development system arecompleted successfully. In conclusion, the research in aspects of hardware design, software design andapplication of embedded system make us learn the core technology of embeddedsystem and setup an firmly base for future complicated embedded development.
