USB 3.0 Device Upgrade IP Core

The USB 3.0 Device Upgrade IP enables designers in the PC, mobile, consumer and communication markets to bring significant power and performance enhancements to the popular USB standard while offering backwards compatibility with billions of USB-enabled devices currently in the market.

Arasan provides designers with a comprehensive, silicon-proven configurable digital USB 3.0 Device solution that conforms to the SuperSpeed specification. The USB 3.0 Device Upgrade is offered to customers with a USB 2.0 Device product interested in adding USB SuperSpeed (5Gbps) capability. It is designed to seamlessly upgrade existing USB 2.0 designs to the USB 3.0 specification for SoC development.

The USB 3.0 Device Upgrade provides a dedicated dual simplex, routable packet architecture for USB3.0 packet transfers, with a disable option for power savings. The USB 3.0 Upgrade IP supports all power management features as well as a dedicated link manager for each downstream port for increased efficiency. It includes a high performance scatter gather DMA that can be configured to access any endpoint through registers. Optionally, it can interface with an external DMA controller.

The USB 3.0 Device Upgrade IP core provides a PIPE interface for USB 3.0 support. The USB 3.0 IP utilizes a flexible system bus architecture that can support AXI, AHB, OCP or any custom system interface needed for existing SoC development. The system bus can also be replaced with a dedicated FIFO interface to reduce bus bandwidth issues. The IP core includes RTL code, test scripts and a test environment for complete design verification.
