摘要
介绍了一种基于SoPC技术的嵌入式数字视频图像采集控制模块的设计方案,通过在CycloneⅡFPGA上配置NiosⅡ软核处理器、ADV7181的I2C配置模块、视频图像采集模块、视频图像解码及颜色转换等相关接口模块来实现硬件平台,并利用Altera公司的软件集成开发环境NiosⅡIDE进行软件设计来控制整个采集流程。对整个系统进行调试,实现了数字视频图像的高速A/D转换、存储及显示等功能。
In this paper, a design scheme of embedded digital video image acquisition module on SoPC technology is introduced. By configuring Nios Ⅱ soft core CPU, I2C configuration module of ADV181, video image acquisition module, video image decoding and color scheme transformation module and some related corresponding interfaces module on a CycloneⅡ FPGA, the hardware platform of the system is constructed, and design software of integrated development environment Nios Ⅱ IDE of Ahera Company is applied to control the whole data acquiring process. The module realizes MD conversion, data saving and displaying of digital video image.
