摘要
通用串行总线技术是一种为实现计算机与各种外设进行数据交换提出的工业标准。它具有快速、双向、支持实时传输、支持即插即用等技术优点。其控制核心包括USB主机控制器和设备控制器。文中设计了符合USB2．0规范的USB设备控制器IP软核。首先通过对USB2．0设备控制器进行分析,为设计划分层次和模块;然后逐个模块地进行结构设计和细节设计;最后对USB设备控制器的设计进行整体逻辑功能仿真。
The general purpose parallel bus technology is an industrial standard proposed for realizing digital conversion between the computer and the peripheral equipment. It has the advantages of high speed, bydirectin, supporting realtime transmission and being able to be used upon insertion. This paper deals mainly with how to design the USB2, 0 device IP core. Based on the transaction dataflow model of the USB device, an USB engine containing a Serial Interface Engine （SIE） and a USB Transceiver Macro - cell （ UTM ） is accomplished. Finally emulation and synthesis is done.
