Design of video transmission card based on PCI bus interface technology

In this paper, the characteristics of CY7C09449 which is a dedicated interface chip for PCI bus are introduced. A design methodology of video data transmission card based on CY7C09449 and FPGA is proposed. Furthermore the timing, the hardware diagram and the program flow of this design are also presented. The result by running in actual system shows that the performance of design is up to the original target, and the card achieves accurate transmission of MPEG-1 video data. The design is also characterized by simple structure and low cost, and it can also be applied in other data transmission and data acquisition through modifying software.
