嵌入式视频采集系统的设计与实现

Design and Implement of Embedded Video Capture System

较为理想的嵌入式视频采集系统是基于DSP的视频采集系统,本文重点阐述了嵌入式视频采集系统的硬、软件设计环节以及开发中的一些关键技术问题。首先以TMS320DM642构建视频采集的硬件系统,详细介绍了TVP5150、SAA7121以及所设计的视频采集系统原理,该系统在Xc2s300控制下能实时将视频像进行采集、编码和传输;最后提出嵌入式系统的开发流程并分析嵌入式系统开发中的一些问题。

Ideal embedded video capture system is the video capture system based on DSP, the paper introduces the design of embedded video capture hardware and software system and some key technology questions. At first video capture hardware system is built using TMS320DM642, TVP5150, SAA7121 and videos capture system principle are introduced in detail, the system can capture, encode and transmit the video picture real-time under the Xc2s300＇ s controlling; the development procedure of the embedded system and some questions of the system is put forward finally.
