    Covering the latest trends and topics in USB IP.

    I’ve been working on USB since the beginning in 1995, starting with the world’s first BIOS that supported USB Keyboards and Mice while at Award Software. After a departure into embedded systems software for real-time operating systems, I returned to USB IP cores and software at inSilicon, one of the leading suppliers of USB IP. In 2002, inSilicon was acquired by Synopsys and I’ve been here since. I also served as Chairman of the USB On-The-Go Working Group for the USB Implementers Forum from 2004-2006.

    I received an M.B.A. from Santa Clara University and an M.S. in Engineering from University of California Irvine, and a B.S. in Engineering from the University of Minnesota. I’m a licensed Professional Engineer in Civil Engineering in the State of California

Synopsys demonstrates SuperSpeed USB 3.0

Posted by ehuang on November 17th, 2008

 

 

 

On November 17, 2008, we demonstrated a USB 3.0 Device streaming uncompressed HD video across a USB 3.0 cable at data rates exceeding 460 Megabytes per second.    To my knowledge, this is the fastest demonstration of USB 3.0 to date, and the only one demonstrating video transfers.  In addition, it is much faster than the targeted 320 Megabytes per second targeted by the USB-IF for effective throughput.  This demonstrates that the protocol is capable to moving data at these rates.  More on this later.

The demonstration consists of 2 PC platforms and 2 FPGA cards.

Let’s start with the FPGA cards.

The 2 FPGA cards are HiTech Global cards with PCI-Express interfaces.  We implement our USB 3.0 Device Controller on one, and a minimal USB 3.0 host capability on the other.  We use Rocket I/Os on the Xilinx Virtex 5 FGPA to implement the necessary signaling over the cable.

The 2 PCs are running a form of embedded Linux that has been stripped down to maximize throughput and minimize OS latencies.  The hardware and application layers are also minimized to create the fastest possible throughput. 

 

I’ll have pictures in a day or so when Wordpress (or my PC) is fixed so I can actually upload the photos.

SuperSpeed USB based on USB 3.0

Posted by ehuang on November 6th, 2008

CNET reported today that USB 3.0 will be “unveiled” at the USB 3.0 Developers Conference on November 17, 2008 just under 2 weeks here in San Jose.  I’m looking forward to the event. 

If you haven’t registered for the event, go to www.usb.org/usb30.  It’s for developers and it’s technical, so keep that in mind.
