摘要
针对传统的车载导航系统终端大多采用单片机为主控处理器,存在处理速度慢,功耗高等问题,提出了采用32位ARM9的嵌入式系统进行控制,研制了新一代的GPS车载导航系统终端。给出了详细的系统硬件电路图,介绍了导航地图的实现。该系统以较少的硬件资源,实现了较高的性能,使得系统具有处理速度快、功耗低、可靠性高等特点。
The traditional vehicle navigation system terminal used single-chip micromputer as the master processor,which existed the disadvantage of slow procosessing speed and high power consumption performance.In view of that,the advanced 32-bit processor-based embedded system is presented and applied effectively in this paper.A new generation of GPS vehicle navigation system terminal is developed.The design method of hardware has been improved.The detailed hardware circuit diagram have been given.
