Due to the characteristics of large amount of data and high rate of transmission in a system of remote image acquisition, a remote image storage system based on low voltage dif- ferential signaling(LVDS) is introduced. The FPGA is designed as the core, and the LVDS in- terface solution string and the drive chip are combined, thus ensuring the effectiveness of re- ceiving remote data. Meanwhile, the alternative two-plane FLASH programming method is a- dopted to storage the image data. It achieves the speed of 28.95 MB/s for storage of real-time image data. Experiments prove that the data storage system is stable and reliable and it can meet practical requirements.
