| Abstract: | In view of the problem that the traditional universal serial bus architecture(USB)interface device has low data transmission rate and can not meet the rapid transmission demand of USB interface data,the design and research of high speed integrated processor USB interface is carried out in this paper.Through high-speed integrated data processing based on OpenVPX,design of USB interface connection mode and initialization of interface register,high-speed communication of USB interface is realized.The experimental results show that the USB interface can effectively improve the rate of data transmission compared with the USB 3.0 interface and meet the needs of real-time high-speed data transmission. |
