| Abstract: | 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. |
