摘要
通用串行总线USB是当前主流的计算机外设接口总线标准,设计实现灵活高效的USB设备控制器具有重要的现实意义.文中基于SOPC技术构建了一个完整的USB2.0设备系统,实现了USB大容量存储设备的功能.由于处理器和USB2.0设备控制器都是以IP软核的形式嵌入到FPGA中,整个系统具有灵活的可配置性.
The USB has become the most popular bus standard of computer＇s peripheral interface, and it is very meaningful to design a flexible and efficient USB Device Controller. A system of USB2.0 device is built based on SOPC in this paper, which acts as a USB Mass Storage device. Because both the processor and the device controller are soft IP cores that can be download into FPGA, the whole system is well configurable.
