摘　　要：根据工业控制的实际需要,简要分析了基于ARM7TDMI-S处理器下实现PC/104总线的可行性。运用CPLD和VHDL硬件描述语言,并通过在μCLinux操作系统下对PC/104总线控制器驱动程序的实现,完成了基于ARM7的PC/104总线控制器的设计。通过实验表明,ARM7微控制器能够很好的支持PC/104总线,并具有低功耗,低成本的特点。为ARM在带有PC/104总线的工业设备和模块上的应用提供了条件。可以使PC/104总线更广泛的应用于嵌入式微控制系统中。In order to meet the requirement of industrial control,this paper briefly analyzes the feasibility of the PC /104 bus based on ARM7TDMI-S processor.Using CPLD and VHDL hardware description language,and through the realization of the PC /104 bus controller driver on μ CLinux operating system,it completed the design of the PC /104 bus controller.The experiments show that ARM7 micro-controller can support PC/104 bus very well and have the characteristic of low power consumption and low cost.It provides conditions for the widely application of ARM on the industrial equipment with PC/104 bus and the module.And it can make the PC /104 bus more widely used in embedded micro-controller system.
