摘要
简要叙述了基于ARM微处理器的车载导航计算机硬件系统的构成和原理,进行了以AT91M40800为核心的导航计算机硬件平台的设计和实验研究,研制了试验样机,进行了样机的仿真调试和有关试验。试验表明,系统各部分运行正常,能对里程计、GPS、数字罗盘等信息进行实时采集和处理,实现了系统的功能要求,为车载导航系统的开发奠定了基础。
An embedded computer based on AT91M40800, for vehicle navigation system, was studied. The hardware was designed and a prototype computer was developed. The emulation debugging and some experiments were done for the prototype. The results show that the prototype computer can properly perform real-time acquisition and procession of data from odometer, GPS and digital compass. The computer can meet the design requirements, and provide the basis for designing a vehicle navigation system.
