摘　　要：SD卡可为便携式裸眼3D设备提供数据来源,图像存储于SD卡中,FPGA以SPI协议方式读出,再经过FIFO和SDRAM进行数据缓存,通过接口输入显示器显示。探讨了通过FPGA器件读取SD卡图像进行显示的实现方法,得出了SD卡文件读取及显示的可行逻辑设计。系统性能经过初步验证,可行性良好。SD card can provide data source for naked-eye 3D devices, image files stored in the SD card, the FPGA read them out in SPI agreement, after the cache in FIFO and SDRAM, the image data enter the LCD screen through the interface. The implementation method of reading image stored in SD card for display using FPGA device is discussed in this paper. And it gets a feasible FPGA logic design of reading and displaying image files in SD card. Through the initial proof, the system has a good performance of feasibility.
