Superspeed Usb For Multimedia Applications

摘要

The USB 3.0 Promoter Group was formed at the 2007 Intel Developer's Forum. Six member companies (HP, Intel, Microsoft, NEC, ST-NXP Wireless, Texas Instruments) developed the initial specification and along with contributor companies created a pool of nearly 200 industry experts to ensure wide acceptance upon release. Finalized in October 2008, the specification was available by mid-November 2008 to any company wanting to adopt it. The most obvious difference in SuperSpeed USB from its predecessors is the over-tenfold speed increase: from 480 Mbits/s to 5 Gbits/ s. While USB 2.0 high speed, and even USB full speed (12 Mbits/s) and low speed (1.5 Mbits/s), are adequate for many applications, the USB connection can become a big bottleneck for others.
