In order to realize the current requirements of video image data memory card such as low power consumption, high storage density, high reading/writing speed, and enhancing the storage medium compatibility with improving the storage capacity and stability at the same time, we suggested a design of Video image data memory card using ATA interface hard-disk, and we use modularized design in this program, consists four parts: the image data buffer module, ATA logic module, ATA interface module, host communication module. Wherein the image data buffer module selects the CPLD plus external FIFO to complete makes the system only need to modify the CPLD program while working together with different external devices, which can improve the reliability and maintainability of the memory card that we designed. The functions of ATA logic module and ATA interface module are realized based on FPGA. The host communication module is completed by the AVR chips with TUSB6250 chip, ensuring the memory card has the advantages of low power consumption, internal short circuit protection and so on. In this paper, the proposed memory card scheme has the superiority such as lower cost, better compatibility, easy to expand, especially suitable for huge amounts of data in video store.
