Design of high-speed integrated processor USB interface based on OpenVPX

文章针对传统通用串行总线(USB)接口器件存在的数据传输速率低、无法满足USB接口数据的快速传输需求问题,展开高速集成处理器USB接口的设计研究。通过基于OpenVPX的高速集成数据处理、USB接口连接方式设计、USB接口寄存器初始化,实现USB接口的高速通信。通过实验证明,该USB接口与USB 3.0接口相比有效提高了对数据传输的速率,满足数据实时高速传输需要。

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.
