USB 3.0 Device Controller
Overview:

Sibridge's USB 3.0 Device Controller is a high performance, low gate count, XDC compliant semiconductor IP designed for SuperSpeed in SuperSpeed USB device implementations ASIC and FPGA and engineered for deep submicron process nodes and smaller geometries.

The controller implements all of the digital layers defined by the USB 3.0 Specification and is fully backward compatible with USB 2.0. User interfaces options include AMBA 2 AHB and a proprietary high-performance DMA.

The diagram below provides a high level overview of the architecture of the device IP. The USB 3.0 device IP seamlessly integrates with wide range of USB 3.0 PHY IP.

The core is compliant with the Intel® PIPE interface for USB 3.0, this allows the core to be integrated with PIPE-complaint PHY layers and also support SSIC interface.
