【Abstract】 According to the requirements of high speed and correctness to the recording system by the CCD camera and comparing the structure of many data recording systems, the FPGA to control the FIFO and the hard disk directly by the ATA protocol are designed. IDE hard disk is used to store the data. High speed, easily to upgrade and work independently are the system’s characteristics. The simulation results under the QuartusⅡ show that the design based on FPGA is correct and feasible.更多还原
