【摘要】 本文设计了DSP+ARM的独立双核结构的嵌入式视频压缩系统。该系统将采集到的连续视频序列按新一代图像压缩标准MJPEG2000压缩后,数据打包发送到网络。本文介绍了系统实现的原理和方法,重点介绍了如何高效地设计ARM与DSP之间的接口以满足嵌入式系统的实时性要求。试验结果表明,各项指标均达到设计要求。该系统为实现远程监控及视频网络传输等提供了解决方案。更多还原

【Abstract】 An embedded video capture and encoding system is designed based on two independent DSP and ARM for real-time video communication over network. The video sequences are captured and encoded in MJPEG2000, and then the data packets are transmitted to user. The hardware principle and software principle of the system are described. In particular, the scheme of how to design the interface between DSP and ARM effectively is described. The system is novel and flexible.更多还原
