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 TVP5150,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.
