| Abstract: | This paper presents a high-speed image transmission system based on optical fiber communication and PCI Express bus. Firstly, the paper introduceS system sCheme and analyses the internal logic of FPGA in detail, including data receiving and delivering on fiber channel and the DMA transfer on PCI Express bus. Then, it briefly introduces the Windows WDM driver and MFC application, Finally, it gives system test results. The system transmission rate can reach 1.5 Gb/s, which meets the need of high frame rate and high resolution image acquisition in most cases. In addition, the system is proved to be ~/ practical design with low cost and easy expansibility. |
