摘　　要：根据硬盘的工作原理,结合ATA标准,在分析现有图像记录系统的基础上,提出了一种由FPGA直接控制硬盘实现实时图像无损记录的存储技术。该技术最大限度地保存了原始图像信息,同时具有受计算机干预小、易于扩展升级、性价比高等优点。目前采用两块IDE硬盘时记录速度达到30Mb/s。According to operating principle of hard disk and combining with ATA standards, a storage technology for real-time image recording without loss implemented by FPGA directly control hard disk is proposed. The technology stores the original image information to the utmost and has advantages such as less computer interference, easily implementing expanding and upgrading, and high cost performance. At present when two pieces of IDE hard disks are used the recording speed has attained 30Mb/s.
