SuperSpeed USB 3.0 Controller
The Snowbush IP USB 3.0 Device Controller is a complete subsystem solution for USB 3.0 Super Speed devices. The core is highly configurable and maintains a low gate count. The Snowbush IP Device Controller is equipped to plug-n-play with the PIPE3 interface on the PHY side, and features a generic Common System Level Interface (CSLI) on the system side. The CSLI integration can easily be connected to any system bus including AMBA AHB and AMBA AXI.
