Infrastructure Hardware And Software Development Of GPS Vehicle Navigation System Based On WinCE.NET

Global Positioning System can effectively improve those problems such as traffic jam,difficulty of destination find,lower efficiency and so on,and bring convenient service to people.It will become the basic equipment of our vehicle. Nowadays,the GPS vehicle navigation system's development is comparatively fall behind in native.According to the researching condition of our own,while by terms of the merit of products now available,the developing of GPS vehicle navigation system based on the platform of ARM and Wince.NET plays a key and base role in the Chinese circumstance,we can find certain theory mean and adaptive value in realization both.This subject designs an embedded GPS orientation system which is based on ARM 9 and used Windows CE as Operating system.This subject is divided into three parts:the development of infrastructure hardware and software,the design of GPS orientation software,the design of digital entertainment.This paper's main task is to design infrastructure hardware and software,and manly includes:Firstly,Analyzing the current research status of GPS vehicle navigation system, giving a new design project of GPS vehicle navigation system basing on the platform of Microsoft's WinCE.NET and Samsung's S3C2440A.Secondly,complete the hardware designing about the GPS vehicle navigation system.The host equipment use S3C2440A as core chip which based on ARM920T kernel,designing FLASH storage module,SDRAM module,UART module and Ethernet module.All of the main chips are small scale and low power consumption, which are fit for the application of embedded system production.Thirdly,Custom operating system kernel and analyses the BSP architecture and developing steps of software parts.Follows that,detailed developing system loader program Boot Loader and others parts of OAL.Fourthly,The anticipated function being realized by module debug and system debug.
