摘　　要：为了实现嵌入式车载系统设计,采用软硬件协同设计技术路线。研究了基于ARM9的S3C2410处理器为核心的嵌入式车载软件的运行机制,包括系统硬件初始化,VxWorks操作系统内核的配置与装载,Vxworks下的LCD显示技术和触摸屏控制技术的应用实现车载仪表信息的显示与交换功能,并通过VxWorks多任务的进行控制。通过实验测试,系统随时进行车载娱乐、自主导航、信息查询等功能。方案实时性好,操作方便。In order to achieve the design of embedded vehicle systems, using hardware and software co- design tech- nology course. Research of S3C2410 embedded processor based on ARM9 as the core operating system,including system hardware initialization, VxWorks operating system kernel configuration and loading, Vxworks under the LCD display and touch screen control technology to achieve vehicle instrumentation information display and exchange functions, and through VxWorks multitasking control. Experimental results of vehicle entertainment system at any time, autonomous nav- igation, and information query. The program real- time, easy to operate.
