摘要
随着SOC技术的广泛发展和USB协议的普遍应用,在芯片设计时嵌入USB设备控制器IP核变得越来越重要。WISHBONE片上总线为IP核的相互通信提供了一种更为简单灵活的实现方法。本文基于WISHBONE片上总线,设计了符合USB2.0协议的设备控制器IP软核,并通过仿真验证,符合设备使用要求。
With a wide range of SOC technology development and application of the universal USB protocol, embedding USB device controller IP core become more and more important in chip design. The WISHBONE bus provide a more simple and flexible method for the communications of IP cores. Based on the WISHBONE bus, the paper designs a device controller IP soft-core according with the USB2.0 protocol. The design can accord with the requirements by simulation and validation.
