基于FPGA和USB3.0的高速CameraLink图像采集

High Speed CameraLink Image Acquisition Based on FPGA and USB3.0

采用Xilinx Artix-7FPGA和Cypress CYUSB3014为核心处理模块,配以DDR3作为帧存,设计了一套高速CameraLink图像采集传输系统。系统利用Xilinx Artix-7自带的ISERDESE资源将串行LVDS的CameraLink视频流转换为TTL并行信号,DDR3存储器作为帧存对输入视频进行缓存,缓存之后的视频信号经过CYUSB3014芯片转换成符合UVC协议的输出数据,通过USB3.0的数据接口发送至PC机,在PC端上能够正常显示。

Using Xilinx Artix-7FPGA and Cypress CYUSB3014 as the core processing device and DDR3 memory as the frame storage,a high-speed CameraLink image acquisition system was designed.Xilinx ArtiX-7 ISERDESE resources are used to convert the CameraLink video stream of serial LVDS into TTL parallel signal,and DDR3 memory is used as frame storage to cache the input video.By CYUSB3014 chip,the cached video signal is converted into output data conforming to UVC protocol and sent to PC through USB3.0 data interface,which can be displayed normally on PC.
