摘要：在分析了ARM处理器系统在指令系统、存储器模型、中断系统、总线时序等方面的特点，研究了IBM PC/AT和PC/104总线规范的基础上，提出了一种在ARM系统中高兼容性地实现PC/104总线的硬件电路方案，以及与之相应的在Linux操作系统中的驱动设计,并讨论了影响该兼容系统性能的相关因素。解决了在ARM系统中无法使用标准PC/104模板的难题。采用该方案，有利于在嵌入式系统的设计中兼顾ARM处理器和PC/AT体系的优势。

Abstract: A PC/104 bus compatible hardware circuit scheme and its device driver design in Linux were proposed, which has solved standard PC/104 device apply in ARM system, based on analyzing the instruction set, memory model, interrupt system, and bus timing, etc. of ARM processor system, and studying IBM PC/AT and IEEE PC/104 bus specification. The influence factors of the compatible PC/104 bus’s capability were discussed. The method helps in the design of the embedded system and concurrently fetches ARM processor and advantage of PC/AT system.
Key words: advanced RISC machines (ARM); PC/104; Linux; device driver; embedded application
