摘要

介绍了一种基于LVDS的高速远程图像数据存储系统.系统以FPGA芯片作为控制核心,采用低压差分信号技术(Low voltage differential signaling,LVDS)接口解串和驱动芯片相结合,保证了有效接收远程数据;采用交替双平面的FLASH编程方式来控制图像数据的存储,实现了以28.95 MB/s的速度对实时图像数据进行存储的要求.经试验验证和实测证明,该图像数据存储系统性能稳定,数据存储可靠,能满足实际测试要求.%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 differential signaling(LVDS) is introduced.The FPGA is designed as the core,and the LVDS interface solution string and the drive chip are combined,thus ensuring the effectiveness of receiving remote data.Meanwhile,the alternative two-plane FLASH programming method is adopted 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.
