摘　　要：PC104总线在嵌入式系统中应用十分广泛,近年来,ARM微控制器凭借其强大的功能,逐渐占据了市场的大部分份额。文中针对利用ARM微控制器控制PC104模块,提出了一套软硬件解决方案;在硬件设计中,FPGA在不同时序的转换中起到了关键性的作用;基于VxWorks操作系统实现了PC104模块的通用驱动设计和库的设计;针对网络应用,实现了基于双缓冲队列的多任务程序设计。PC104 bus is widely applied in the embedded system, and ARM microcontroller, resorting to its formidable advantages, gradually occupies the major share of the market in recent years. Proposed a set of hardware and software solutions to the control of PC104 module with ARM microcontroller. And in the conversion of different tinting, the FPGA played a key role. Based on the VxWorks operating system, implemented designs of the general drive and library, and in the end, according to network application, achieved the multi- task program design based on the double - buffer queue.
