| Abstract: | To solve the Camera Link video image signal acquisition and display problems, a design based on PXI system platform was presented. FPGA used strong parallel processing ability and internal rich resources of block RAM to design four modules of PXI interface, Camera Link data receiving, SDRAM cache and VGA display control. The design realized display of double-images by controlling video conversion chip ADV7123 and using FPGA to construct VGA timing. The test result shows that the system can achieve 100MB/s image data real-time display ,satisfy the expected effect and possess certain practicability and popularization value. |
