摘要
介绍一种基于复杂可编程逻辑器件(CPLD)和数字信号处理器(DSP)的图像采集系统。系统采用增强型视频输入处理芯片SAA7111A完成视频信号的A/D转换,利用CPLD实现对视频前端译码后的视频数据的存储,以及完成前端采集与后端处理协调工作的方案。按照该方法制作的系统,经过实验验证效果良好。
This paper introduced an image collection system based on CPI.D and DSP. The system uses enhanced video input processor SAA7111A to accomplish A/D conversion of video signal,and uses CPLD to accomplish the video data＇s saving and the project which makes the collection part and the processing part work in phase. A system has been made according to this method and the feasibility is demonstrated.
