基于DM642 DSP技术视频图像采集与传输系统设计

Video Image Acquisition and Transmission System Based on DM642 DSP

摘要:

视频图像的采集与传输技术一直是信号处理领域研究的热点与难点问题,文章主要以系统的硬件设计和软件设计来对系统进行详细论述,在硬件设计中,通过分析视频图像采集所需要的主要性能指标,确定了系统采用TMS320DM642 DSP芯片,并确定系统的总体设计方法,同时完成了DSP最小系统设计,电源设计以及图像传输模块设计等；在软件设计中,通过对DSP实际控制,从而实现了系统的视频编码余打包等功能,并完成了视频传输的驱动程序设计,最后通过对TMS320DM642 DSP的实时控制,实现视频图像传输与采集功能。

Abstract:

the acquisition and transmission technology of video image is always a hot and difficult issue in the field of signal processing, in this thesis, the hardware design and software design of system are discussed in detail, in the hardware design, through the analysis of the main performance index of video image acquisition needs, the system uses TMS320DM642 DSP chip, and the method of determining the overall design of the system, also completed the DSP minimum system design, power design and image transmission module design; in software design, through the actual control of the DSP, thus realizing the video image acquisition and transmission.
