采用高速缓存、帧分多路输出，实现一种实时大图像多显示器联合显示系统。该方案采用现场可编程逻辑阵列芯片，利用双倍速率同步动态随机存储器芯片作为数据缓存单元，通过片上同步动态随机存取存储器乒乓缓存数据，将每帧图像数据平均分配并通过相机连接（Camera Link）接口发给上位机显示。通过Chipscope在线调试软件测试，该实时显示系统支持5路Camera Link输出，每路Camera Link图像输出采用12比特位宽，支持最大数据吞吐量为960M bps ，能解决超大尺寸图像因常规显示器显示范围有限而不能在一个显示器上完整显示的问题。

A real‐time oversized image multi‐monitor display system is achieved by adopting high‐speed buffer and framing multipath‐output in this paper .The system is realized in a field pro‐grammable gate array (FPGA) chip .In this scheme ,double data rate synchronous dynamic ran‐dom access memory (DDR SDRAM ) chips are used to buffer oversized image data .The image da‐ta are distributed averagely by synchronous dynamic random access memory (SDRAM ) ping‐pong buffer ,then transmitted to principal computer via a Camera Link connector ,and displayed in screen of PC .Tested results from Chipscope online debug software illustrate that the real‐time displaying system supports 5 channels output of Camera link ,the bit width of each Camera link is 12bits ,and the highest throughout of image data of each Camera link is 960M bps .T hese mean that the proposed system can solve the problem that oversized image cannot be displayed in one single displayer w here the display range of displayer is limited .
