基于PCIE的高速光纤图像实时采集系统设计

Design of high-speed real-time fiber image acquisition system based on PCIE bus

利用PCI Express(PCIE)总线及DMA数据传输技术,设计光纤图像实时采集系统。利用FPGA中的PCIE硬核实现了PCIE总线的DMA传输,同时介绍了整个采集系统的数据流和光纤接口模块的设计。测试结果表明,系统DMA数据传输速度可达到138 MB/s,完全满足高速光纤图像实时采集的需要。

PCIE technology and DMA technology are used to implement the real-time fiber image acquisition system.The paper focuses on how to implement DMA transmission on PCIE hard core and introduces the data stream of the system and the custom protocol of high speed serial fiber transmission.The test result shows that the DMA speed can reach 138MB/s,so the system fulfils the need of high-speed real-time fiber image acquisition.
