摘　　要：本文提出了一种低成本高性能的基于TI公司的TMS320C6711的数字图像处理系统的设计方案。通过采用功能全面的视频解码器并辅以DSP软件,本系统可以兼容多种视频格式,采用高速FIFO完成视频解码器和DSP之间的互联,实现视频图像数据的高速缓冲。利用TMS320C6711的McBSP功能单元,通过软件模拟I2C接口实现了对视频解码器的控制,文中既给出了硬件系统设计方案,也给出了软件系统设计流程。利用TMS320C6711强大的处理能力,通过开发不同的软件,本系统可以应用于各种嵌入式图像处理系统中,具有很强的实用性和先进性。This paper puts forward a kind of low cost high performance of obtain system with the processing digital picture based on the TMS320C6711 of the TI company. Pass the adoption function overall video decoder and assist with the match of the software, the system can permit various video frequency formats, and this system uses high-speed FIFO implementing the interconnection between the video decoder and DSP to achieve the high speed buffering of the video data. This system implemented the I^2C interconnection between the video decoder and TMS320C6711 through software simulation using TMS320C6711′s McBSP functional unit. This paper not only gives the hardware system design project, but also gives the software system design process. Profitted from, the powerful processing ability of TMS320C6711 DSP,through developing different software, this system can be applied to all kinds of embeded image processing systems. So it is more practical and advanced.
