为了代替PC机对高帧频数字图像进行实时采集显示，使用片上系统(SOC)和可编程片上系统(SOPC)的设计方法，设计了基于NiosⅡ软核的嵌入式图像采集显示系统。依据系统功能需求设计出系统架构，给出了系统各个功能模块的设计方法，对系统中接口模块的信号时序和图像数据缓存处理架构进行了软件编写及仿真。描述了应用该系统所进行的高帧频图像采集显示实验，并分析了系统性能。实验结果表明：对于帧频高达1 230帧/s、分辨率为128×128的图像源，该系统可以对其进行实时的采集显示。满足了降低成本、节约空间、提高系统稳定性和工作带宽的要求。

In order to replace the PC system for high frame rate digital image acquisition and display based on camera link interface, an embedded system based on SOPC and NiosⅡ has been developed. System construction is designed according to functional requirement, and the design method for each functional module of the system is presented. Then signals of interface module, image data storage and process module have been programmed and simulated. Finally, the experiment of system for high frame rate digital image acquisition and display is described and analyzed. Experimental results indicate that high frame rate image which resolution is 128×128, and transferred at 1 230 frames/s can be grabbed, processed and displayed by designed system. It can satisfy the system requirements of lower cost, saving space, improving system stability and work bandwidth.
