USB设备控制器IP核设计与FPGA验证

Design and FPGA verification of a high-speed USB device controller IP core

主要研究USB设备控制器IP核的实现方法。介绍了USB系统体系结构,划分USB设备控制器模块,着重介绍了高速检测和枚举过程,最后用Verilog硬件描述语言实现了USB设备控制器IP核的设计,并用FPGA进行了验证。验证结果表明,该IP核能实现USB设备和主机间的正常通信。

The implementation of USB device controller IP core is described in this paper. The USB system architecture is firstly clarified and the block diagrams of the design are shown. High speed detection and enumeration are described specially. The design is implemented by Verilog HDL and verified in FPGA. The result indicates that this IP core can communicate with USB host.
