摘要
根据基于ARM处理器的数控系统的需要,通过对EP9315开发板的研究与实验,提出一种在ARM数控系统上实现PC/104总线的方案,用于读写运动控制卡。采用CPLD和VerilogHDL语言,描述了PC/104总线控制器的实现方法;介绍了在Linux操作系统下PC/104总线控制器的驱动程序的开发。实验结果表明基于ARM处理器的数控系统能够支持PC/104总线,能够使ARM处理器能够更广泛的应用于数控领域。
In order to meet the requirement of ARM CNC, the paper presents a design of PC/104 bus based on ARM CNC that can read and write motion controller card after having research and test on the platform of EP9315.h emphasis on controller of PC/104 bus by applying CPLD and Verilog HDL language, and introduces approach designing device drive of PC/104 bus controller in Linux operation system. The results indicate that the ARM CNC can support PC/104 bus and ARM processor can be used in CNC widely.
