USB3.x HOST IIP

Overview

USB3.x Host interface provides full support for the USB3.x synchronous serial interface, compatible with USB 3.0/3.1/3.2 specification. Through its USB compatibility, it provides a simple interface to a wide range of low-cost devices. USB3.x Host IIP is proven in FPGA environment. The host interface of the USB3.x Host can be simple interface or can be AMBA AHB, AMBA AXI, VCI, OCP, Avalon, PLB, Tilelink, Wishbone or Custom protocol.

USB3.x HOST IIP is supported natively in Verilog and VHDL
