由于目前基于CameraLink接口的各种相机都不能直接显示，因此本文基于Xilinx公司的Spartan 3系列FPGAXC3S1000-6FG456I设计了一套实时显示系统，该系统可以在不通过系统机的情况下，完成对相机CameraLink信号的接收、缓存、读取并显示 系统采用两片SDRAM作为帧缓存，将输入的CameraLink信号转换成帧频为75Hz，分辨率为1 024×768的XGA格式信号，并采用ADV7123JST芯片实现数模转换，将芯片输出的信号送到VGA接口，通过VGA显示器显示出来-As the CameraLink interface is currently based on a variety of cameras can not directly display, this article based on Xilinx' s Spartan 3 series FPGAXC3S1000-6FG456I designed a set of real-time display system, the system can be achieved without machine case through the system to complete the CameraLink cameras signal reception, cache, read and display systems use two SDRAM fr a me buffer as the input signals into the CameraLink fr a me rate of 75Hz, a resolution of 1 024 × 768 for XGA format signal, and using ADV7123JST chip digital-analog conversion, the chip output signal to the VGA port, through the VGA display monitor
