基于FPGA的USB视频传输系统设计

本设计以高清CCD模块采集到的可见光视频图像通过USB实时传输到PC机为例,阐述USB视频系统的设计。系统使用OmniVision的OV5640 CCD图像传感器作为光电成像器件,采用USB2.0控制器芯片CY7C68014A与FPGA直连,通过FPGA对高清CCD模块的视频数据进行处理并传输到USB芯片上,最后在PC机上实时显示。该设计结构简单,使用方便,便于大型系统的设计。通过该设计实现高清CCD的USB实时传输,已在相关手持设备产品中进行应用。

USB Video Transmission System Based on FPGA

The module is designed to capture high-definition CCD visible, and then transferred video images via USB to a PC in real-time. The system uses OmniVision＆#39;s OV5640 CCD image sensor as a photoelectric device,and With USB2.0 controller chip CY7C68014A directly connected with the FPGA. Through the FPGA video data from the high-definition CCD module was processed and transferred to the USB chip, and finally displayed on the PC. The design is simple, easy to use, and fitted for large-scale systems. The design and implementation of real-time transmission of high-definition CCD via a USB have been conducted in the handheld products.
