Fresco Logic Demos SuperSpeed USB Host and Device Prototypes

Fresco Logic, Inc., a silicon IP, chip and solution company, demonstrates SuperSpeed USB data transfer running under Microsoft’s Windows Vista Operating System in the USB TechZone at the CES (Consumer Electronics Show) January 8-11 in Las Vegas. The demonstration marks the first public showing of a working SuperSpeed USB xHCI host controller adapter supporting beta xHCI driver in a PC running Windows Vista. The PC is connected using the 2 meter new USB 3.0 cables to Fresco Logic’s SuperSpeed USB Mass Storage Device prototype hardware. The USB TechZone is at the Las Vegas Convention Center South Hall 3 and is sponsored by the USB-IF.

USB 3.0 Host

The demonstration features SuperSpeed USB performance testing, file drag and drop, real-time video streaming, plug and unplug capabilities between the USB 3.0 Host and Mass Storage Device (MSD). The demonstration utilizes Fresco Logic’s xHCI Host Controller and USB 3.0 Device Controller Intellectual Property that is compliant to the latest xHCI specification and newly released Rev 1.0 USB 3.0 specification. Using the existing mass storage device client driver the throughput measured by real-time performance test in the demonstration can reach up to 250 Megabytes per second. SuperSpeed USB is well positioned to exploit the additional performance capacity as new technologies are deployed, for example, a new mass storage class specification in the future. The demonstration highlights the ability of SuperSpeed USB to deliver significant benefits while preserving the bulk of the software infrastructure; providing immediate and easy access to SuperSpeed USB bandwidth for next generation NAND flash storage, external HDD, and HD video streaming applications that demand higher bandwidth than Hi-Speed USB can provide.

Fresco Logic is working with leading Systems and IC companies to develop Host and Device based SuperSpeed USB products. Working with early adopters Fresco is putting its USB technology into products that will enter the market in late 2009.
