Abstract
The invention relates to a TMS320DM642-based video image processing system. A camera inputs a composite video signal into a video decoding chip, an analog video is digitally processed and an image signal and a synchronous signal are separated in the video decoding chip, digital image data output by the video decoding chip enters a FIFO of a DSP video input port to be cached and is sent to an external memory module of a DSP module through an EDMA, and the processed image is stored in an output cache and transmitted to an external main device through a PCI bus interface. According to the TMS320DM642-based video image processing system of the invention, a TMS320DM642 chip specifically used for multimedia processing is used as a processor, the overall cost performance of the system is improved, video capturing is completed by the adoption of a special decoding chip, and image processing is carried out more efficiently.
