Description

technical field [0001] The invention relates to an FPGA-based Camera Link interface experiment and development system, especially suitable for FPGA-based Camera Link interface experiment and application development, and belongs to the technical field of digital logic design and high-speed data transmission. Background technique [0002] Camera Link is a high-speed image data transmission protocol. It is a communication interface technical standard for machine vision applications jointly proposed by NI, camera equipment suppliers, and some image acquisition companies at the beginning of this century. Using this protocol can simplify the image acquisition interface, making the connection between the camera and the data acquisition card more convenient. Camera Link interface is developed on the basis of Channel Link transmission technology. Channel Link technology is a technology developed by National Semiconductor Corporation based on low-voltage differential signaling (LVDS)...
