摘要
随着信息科技技术的深入研究与应用,在很多行业领域都应用到视频图像。该文对视频图像处理系统设计分析与研究关键通过SoPC及FPGA两大处理技术。系统采用视频转换芯片SAA7113完成视频图像采集模块的设计,采用CY7C1049 SRAM完成图像数据的存储,设计VGA显示输出控制关联模块,同时重新修改了显示芯片具体运作形式的配置信息,相结合产生VGA具有控制能力的信号;参考VGA显示器的运行原则,实现了VGA帧一致性信号与接口水平的提升。
With the further research and application of information technology,video images are applied in many fields. The video image processing system based on two processing technologies of SoPC and FPGA was designed and analyzed. The vid-eo conversion chip SAA7113 was adopted in the design of video image acquisition module. CY7C1049 SRAM was used to com-plete image data storage. VGA display and output control module was designed. The configuration information of the operation mode of the display chip was modified,with which VGA work control signal was generated. According to the industrial standard of VGA display,the improvement of the VGA interface level and frame synchronization signal was realized.
