Cadence Design Systems Inc. has added a host controller intellectual property (IP) for USB 3.0 to its IP offering. The Cadence USB 3.0 xHCI host controller IP was originally developed by Fresco Logic, a global fabless semiconductor company that develops and markets advanced connectivity solutions.

This design IP is used as part of a recommended Peripheral Development Kit (PDK) for compliance testing by the USB Implementers Forum (USB-IF) and has been deployed in over a billion USB ports. Being part of the compliance test ensures interoperability with the large number of USB peripheral controllers available in the market.

Now licensed by Cadence, the USB 3.0 xHCI host controller is being offered as fully supported semiconductor IP. Cadence also has an agreement with Fresco Logic to license the next generation of this host controller IP supporting the USB 3.1 protocol.

The Cadence USB 3.0 xHCI host controller IP provides SoC designers with a way to implement a USB interface in their applications. The IP is architected to quickly and easily integrate into any SoC as an integrated solution with any Cadence or third-party USB PHY IP. Host applications access the controller through the industry-standard ARM AMBA AXI system bus with an optional PCIe interface.

"The addition of the USB 3.0 and USB 3.1 xHCI host controller IP completes the Cadence USB portfolio, complementing our premium USB PHY design in the most advanced process nodes," said Martin Lund, SVP, IP Group, of Cadence. "Our customers now have immediate access to a complete solution that enables their products to work effectively, meet compliance quickly, and get their products to store shelves sooner."

The Cadence USB 3.0 IP is fully configurable, allowing customers to achieve the optimised functionality they require, whether it is for mobile or infrastructure applications.
