【摘要】 在视频压缩系统中,视频解码器输出的BT.656数据流不便于TMS320C6416等通用DSP直接进行处理。本文介绍了一种基于FPGA+DSP构架的视频采集方案,通过对FPGA的灵活配置,对输入的BT.656格式视频信号进行预处理和缓冲。系统采用TI的TMS320C6416作为核心DSP,实现了高可靠性的视频压缩。更多还原

【Abstract】 In video compression system, the BT.656 data stream generated by video decoder can not be easily processed by general purpose DSP like TMS320C6416. In this paper, a system based on FPGA + DSP architecture is introduced. By configuring the FP-GA, the system preprocesses the BT.656 data stream and works as a buffer for the DSP. TMS320C6416 of TI is used as the core DSP for the system.更多还原
