In the light of the characteristics of the large amount of data and the high rate of transmission in the image acqui- sition system, the solution scheme which applys the PCI bus protocol for achieving communication between PC and the data storage system and LVDS bus protocol for data transmission and mixed coding is proposed. In order to improve the rate of data storage, the interleave two-plane page programming techniques is adopted, and the writing rate can be improved to be 30 Mbyte/s, which fully fulfils the requirement of high-speed storage of the image data. Meanwhile, on-chip FIFO buffer is built
