摘　　要：为了实现高速、大容量的图像数据传输,讨论一种基于USB 2.0协议的高速图像数据传输方法。该方法以接口芯片CY7C68013A为数据传输核心,克服了传统接口局限,支持热插拔和即插即用,有效地解决了计算机和外设之间高速、大容量的图像传输问题。详细描述系统各部分的软、硬件设计,并在实际应用中实现了图像数据的高速传输。测试结果表明,系统传输速度可达到192 Mb/s,它在各种高速数据传输领域有着广泛的应用价值。For the realization of high and mass image data transmission,a method of high speed image data transfer based on USB2.0 protocol is introduced. This design is based on interface chip CY7C68013A as a main data transmission unit,overcomes the limit of traditional interface, supports hot attach - and - detach, plug ＆ play, and the mass and high speed transmission of image between computer and external cache is realized in effect. Software and hardware design of parts of the system are described in details. The high and mass image transmission has been applied in practical system. Experimental results show that the system can achieve the data transfer speed of 192Mb/s,and it also has a lot of applications in the areas where need mass and high speed data transmission.
