Abstract: This paper presents the function, architecture, the sub-module circuit design and implementation of USB1.1 OHCI host controller IP. Itaddresses the host controller serial engine and its clock and data recovery circuit and parallel cyclic redundancy check (CRC) arithmetic. To verifythe OHCI host controller’s function, the system level verification is done on the ZhongKe-SoC virtual verification platform, and the resultsdemonstrate the correctness of the design.
