基于SOPC的视频画面分割器的设计
Design of Video Multiplexer Based on SOPC
【摘要】 研究一种基于SOPC技术的视频画面分割器的设计。该系统通过在FPGA芯片上配置NiosⅡ软核处理器和相关的接口模块来实现其主要的硬件电路,并结合系统的软件设计来控制多路高速多功能视频解码芯片ADV7181,实现对图像数据的高速采集、有效抽取及压缩、存储、画面数据合成及显示等功能。
【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.
