[Abstract]:USB serial universal bus is widely used in computer peripherals because of its convenience, plug and play and hot plug and play. At present, USB2.0 is widely used in various fields, but limited to its low transmission rate, it can only be used for medium and low speed transmission. For high speed image data, video data transmission has some limitations. The white paper of USB3.0 standard was officially released in 2008, and the transmission rate reached 5Gbps. The transmission rate is comparable to that of Camera Link bus and IEEE 1394. At the same time, it has the characteristics of supporting hot-plug, simple interface structure and low requirement for PC interface. The appearance of USB3.0 is a milestone in the development of Universal Serial bus. USB3.0 will become a popular trend of transmission bus. The Camera Link bus will be replaced by IEEE1394 in certain application fields. With the development of information age, high-speed data acquisition is becoming more and more important in our life and scientific research field. How to achieve high-speed data acquisition is an important issue. Firstly, several high-speed buses are introduced, and the advantages of USB3.0 data bus are analyzed. Then the principle and advantages of USB3.0 transmission are analyzed. This design realizes the high-speed data acquisition based on USB3.0. High-speed image data is generated by simulation, cache is realized by DDR2, and high-speed image data is transmitted by USB3.0 high-speed bus. Complete USB3.0 firmware development, application development, will receive data storage display. The experimental results show that the high speed data acquisition up to 2Gbps can be achieved. In the data storage part, the solid-state disk array is used to realize high-speed data reading and writing. In this paper, the research on the transmission of high speed image data by USB3.0 lays a great foundation for the application of USB3.0 high-speed bus in camera system, and it is convenient for subsequent application development.
