摘要
针对视频图像信号数据量大,传统的USB 2.0和以太网传输速率有限,不能满足视频快速传输的问题,文中设计一种基于USB 3.0的超高速数据传输系统。通过对USB 3.0接口电路、设备固件及接口器件中SLAVE FIFO(同步从设备FIFO)模式与中控单元读写操作的设计,实现数据的高速、可靠传输。经过模拟测试和实际传输测试,该系统能够实现视频图像信号的高速传输,传输速度可达320 MB/s,且数据稳定。所设计的接口系统功能强大,接口简单,可适用于各种需要高速数据传输的场合。
As the traditional USB 2.0 and Ethernet have limited transmission rate for the large amount of video image signal data,which cannot meet the needs of fast video transmission,a ultra⁃high⁃speed data transmission system based on USB 3.0 is designed.The USB 3.0 interface circuit,SLAVE FIFO mode(synchronous slave FIFO)in device firmware and interface device and read and write operation of central control unit are designed to realize the high⁃speed and reliable data transmission.After simulation test and actual transmission test,the system can realize the high⁃speed transmission of video image signal,the transmission speed can reach 320 MB/s and the data is stable.The designed interface system has powerful functions and simple interface,which is suitable for various occasions requiring high⁃speed data transmission.
