摘　　要：根据CompactFlash(CF)规范,设计了一种基于FPGA的CF卡端接口,实现了存储器模式和I/O模式两种方式的接口设计,可作为大部分便携式I/O设备的接口,硬件测试证明本文设计的CF接口可正常与上位机通信.与基于独立接口转换芯片的设计方案相比,本方案设计灵活,系统成本和功耗更低.By reading CompactFlash specification, a CF card side interface based on FPGA with memory mode and I/O mode is designed, which is applied to most kinds of portable I/O devices. The CF card side interface is proved to successfully communicate with host by test. The design has more flexibility, lower system cost and power consumption, compared to traditional designs based on special interface chips.
