基于NiosⅡ多核智能交通车载终端的设计与实现

Design and implementation of intelligent traffic vehicle terminal based on NiosⅡ

利用NiosⅡ多核处理器,提出了基于Internet的实时路况查询系统和智能车载终端。通过配置双NiosⅡ软核,改善了MCU处理速度不高、外设资源有限、接口配置繁琐、硬件设计和软件设计编程复杂等问题,将大量控制以及对多种外设访问的工作进行了合理分配。既具有普通导航设备的方便实用性,又能通过无线通讯及Internet与后台服务器连接,获取道路拥堵情况、停车场车位情况等动态实时信息,同时可作为智能交通的车载前端。

Using NiosⅡ multi-core processor,based on the Internet real-time traffic query system and intelligent terminal. Through the configuration of double NiosⅡ core, MCU improved the processing speed is not high, limited resources, peripheral interface configuration is complicated, hardware design and software programming of complex issues, a control and a variety of peripheral access work allocation. Not only has the ordinary navigation equipment is convenient and practical, but also through the wireless communication and Internet and background server, access road congestion, parking and real-time dynamic information, at the same time as the intelligent traffic vehicle front end.
