USB 2.x Hub IP
Overview
USB 2.x HUB interface provides full support for the USB2.x synchronous serial interface, compatible with USB 2.0 specification. Through its USB2.x compatibility, it provides a simple interface to a wide range of low-cost devices. USB2.x HUB IIP is proven in FPGA environment. The host interface of the USB2.x HUB can be simple interface or can be AMBA AHB, AMBA AXI, VCI, OCP, Avalon, PLB, Tilelink, Wishbone or Custom protocol.
