[Abstract]:High frame rate and high resolution image acquisition is widely used in high-tech research, industry, medical treatment, transportation, aviation and many other fields, such as high-speed object trajectory capture 3D animation, video location and measurement in aerospace and military industry. Highway traffic monitoring and so on. However, the continuous acquisition of this kind of image will produce a huge amount of data. How to transmit these massive image data to the computer for analysis and processing in real time and remotely becomes a subject that must be studied. Optical fiber communication technology has the advantages of low frequency bandwidth, low loss and strong anti-interference ability. It can meet the requirements of high-speed data long-distance transmission. PCI Express bus has obvious advantages over PCI-X bus. In particular, the rate has been greatly improved. The single channel one-way rate of PCI Express 1.0 is up to 2.5 Gbpss, and the maximum support is 32 channels. Based on the advantages of optical fiber communication technology and PCI Express bus, a high-speed data transmission system is designed in this paper, which can realize the real-time and remote transmission of high-speed image data to computer. In the aspect of hardware, PCI Express optical card is designed with Xilinx Spartan-6 LXT series FPGA as main controller, PCI Express bus protocol is realized by using PCI Express hard core in FPGA, and SFP optical module is driven by GTP high-speed transceiver to realize optical fiber communication. The internal logic design of FPGA is carried out by using Verilog HDL. The functions of PIO operation, interrupt control and DMA transmission of Express bus are realized, and every function module is simulated and tested strictly. In the aspect of software, the driver of PCI Express fiber card is developed by using Windows DDK. The driver model of WDM is used to realize the functions of interrupt response programming, hardware register reading and writing and application program interface. On the basis of driver, an application program based on MFC is designed in Visual C development environment, which can receive, display and store images. In the application program design, many kinds of programming techniques, such as multi-thread technique and DrawDib drawing, are used to greatly improve the software performance. At the end of the paper, the system debugging flow and performance analysis are given. The test results show that the transmission speed of the system is as high as 1.2 Gbps.The system can transmit images stably and reliably.
