中科SoC的USB1.1OHCI主机控制器IP设计

USB1.1 OHCI Host Controller IP Design for ZhongKe-SoC

系统阐述了USB1.1OHCI主机控制器IP的功能、结构、各功能模块的电路设计和实现方法,介绍了主机串行接口引擎模块及其时钟和数据恢复电路以及并行CRC算法的设计。为了验证OHCI主机控制器功能正确性,在中科SoC虚拟验证平台上对该主机控制器做了系统级模拟验证,验证结果证明了设计的正确性。

This paper presents the function, architecture, the sub-module circuit design and implementation of USB 1.1OHCI host controller IP. It addresses the host controller serial engine and its clock and data recovery circuit and parallel cyclic redundancy check （CRC） arithmetic. To verify the OHCI host controller＇s function, the system level verification is done on the ZhongKe-SoC virtual verification platform, and the results demonstrate the correctness of the design.
