| Abstract: | 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. |
