基于TMS320DM6446的嵌入式视频处理模块硬件设计

采用TI公司的DaVinci系列芯片TMS320DM6446为主芯片设计了一套视频处理模块，该模块通过高速视频解码电路对模拟视频信号进行数字化处理，由DSP（数字信号处理器）芯片对数据进行处理，从而实现实时处理和输出。详细介绍了视频处理模块的硬件设计方案，主要涉及到视频解码芯片TVP5150、FPGA（现场可编程门阵列）及DSP等，还包括视频协处理电路和网络通信及接口电路。所提出的系统设计方案满足嵌入式视频处理要求，可作为最小的独立视频处理系统运行。

Hardware Design of an Embedded Video Processing Module Based on TMS320DM6446

A video processing module using TI＇s DaVinci chip TMS320DM6446 as the main chip is described in this paper. In this system analog video signal is digitized by a high-speed video decoding circuit and computed by the DSP chip to achieve real-time processing and output. The hardware is made up of a special video decoder TVPS150, FPGA and DSP, and the circuits include video processing, network communication and other interface circuits. It achieves the basic requirements of embedded video processing and can be used as a minimum independent video processing system.
