摘　　要：该文通过对S3C2440开发板的实验和研究,提出一种ARM嵌入式系统上实现PC104总线方案。通过CPLD芯片实现PC104总线功能。通过实现PC104总线相关信号之间的时序来完成ARM9芯片与外部设备之间的操作。实验结果表明,通过CPLD芯片可以很好地完成PC104总线功能。This paper presented a kind of scheme to realize PC104 bus, which based on the ARM embedded systems, by having a test and research on the platform of S3C2440. This scheme realized the function of PC104 bus through the CPLD chip, and completed the operation between ARM9 chip and external equipment by im- plementing the timing of PC104 bus related signals. The experiment showed that the function of PC104 bus can be performed well by the CPLD chip.
