Abstract: | This paper discusses a design of video-multiplexer based on SOPC technology.By configuring Nios Ⅱ CPU and some corresponding interface modules on a FPGA to construct the module’s hardware,and combine software programming to control high speed decode IC ADV7181 and SDRAM,the module realizes high speed data acquisition & compression,synthesis and saving of image signal.Because the high speed parallel process of FPGA,flexible synthesis of multi-video and digital image process algorithm is adopted,it achieved real time multi-video data display. |
