Renesas Electronics Collaborates with AMD to Accelerate Promotion of USB 3.0 Standard
Renesas announced its collaboration with AMD to promote the new SuperSpeed Universal Serial Bus (USB 3.0) standard. In December 2009, Renesas Electronics (formerly NEC Electronics Corporation) released its USB Attached SCSI Protocol (UASP) driver, supporting the new industry-standard, highly efficient mass-storage protocol suitable for use on SuperSpeed USB to overcome the performance boundaries of the Bulk Only Transfer (BOT) protocol.
The To continue to drive market leadership and meet the demand for USB 3.0, Renesas Electronics has been collaborating with AMD to accelerate the promotion of USB 3.0. Adopting Renesas Electronics' USB 3.0 xHCI host controller to its reference design, AMD successfully implemented USB 3.0 data transfer speeds onto its motherboards. Renesas Electronics and AMD are also partnering to achieve interoperability of Renesas Electronics' UASP driver with AMD's motherboards to provide a standardized UASP driver into the market. AMD successfully enhanced the data transfer rate by around 20 percent compared to the conventional BOT., while minimizing design-cycle time.
We're very pleased with the performance and cost ratio of our USB 3.0 portfolio that we've been able to achieve due to our collaboration with Renesas Electronics, and how this can offer even more value to our customers, said Mike Wisor, Senior Director of System Software Development at AMD. By combining both companies' innovation and expertise, we were able to enable the USB 3.0 ecosystem for UAS support, further increasing the performance of these USB 3.0 solutions. We are pleased to share our USB 3.0 host controller and technologies with AMD to develop their USB 3.0 product portfolio by reducing time-to-market, lowering power consumption, and improving price-performance, said Kazuyoshi Yamada, senior vice president, Renesas Electronics Corporation. Starting with AMD's motherboards, AMD and Renesas Electronics will continue to work together as the industry leaders to expand the USB 3.0 marketplace offerings with the highest quality and significantly advanced data transfer speed to provide added value to our customers in consumer and portable electronics.
