本文设计的是基于大规模FPGA的BMP图库管理，完成了数码相框的一部分功能。并且本文详细地介绍了BMP图库管理的软硬件实现，即采用Altera的CyclonII系列EP2C20F484C7作为主控芯片，内嵌32位的NiosII软核，采用SDRAM作为内存，把存储在SD卡内的二进制图片信息读入内存，并控制TFT彩色液晶，读取图片数据送到液晶上显示。整个过程的所有设备都是通过Avalon总线挂在NiosII上，在NiosII的协调下正常工作。
本作品最终能显示存入SD卡内的彩色图片信息，图片显示很流畅，没有延时。并且能通过4个按键分别完成图片的上翻、下翻、放大和缩小。-This design is based on the large-scale FPGA-BMP library management, and completed part of the features of digital photo fr a me. This paper describes the library management software and hardware to achieve BMP photos, that used the Altera s CyclonII series EP2C20F484C7 as the master chip, embedded soft-core 32-bit NiosII, the use of SDRAM for memory, SD card stored the binary picture information read into memory, and control TFT color LCD, read the image form the memory data to the LCD display. All equipment of the process hanging in the NiosII through Avalon bus, with the NiosII CPU and complete the coordination of work.
Eventually the work can show the color pictures of information stored into the SD card, pictures show smoothly, and with no delay. And with 4 keys, respectively, we can make the TFT display the previous image or the next image,and make the pictures zoom in or zoom out.
