This design is composed with two parts, hardware circuit design and EDA design of FPCA. Starting from the hardware system,this design introduces the principle of the hardware system and it's components;Focus is put on the function modules within the FPGA, including Camera link interface module, forward FIFO control module,SDRAM control module,ping-pong operation control module,backward FIFO control module,DVI video display control module. Experiments show that the system can achieve a perfect DVI display of digital camera output video, with advantages such as low cost and wide application.
