High Frame Rate Digital Image Acquisition and Display System Based on SOPC
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 128128
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.
