To USB or Not to USB: A USB IP Blog
  • About

    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

USB 3.0 and DDR at DesignCon

Posted by Eric Huang on February 3rd, 2010

We demonstrated our USB 3.0 PHY and USB 3.0 Device controller at DesignCon in Santa Clara this week.  We also demonstrated our DDR PHY and controller as well.

We will have a more extensive video of the USB 3.0 PHY/Core demo shortly.  Here’s a short Video log from the show floor.

DisplayLink USB 3.0 Demo with Synopsys USB 3.0 IP and HDMI IP

Posted by Eric Huang on January 29th, 2010

Dennis Crispo, Vice President of Marketing for DisplayLink demonstrates the DisplayLink USB 3.0 prototype using Synopsys USB 3.0 Digital Device Controller IP and HDMI Digital Tx Controller IP.

 

With the 10x speed improvement over USB 2.0, the 5Gbps SuperSpeed USB 3.0 connection enabled Displaylink to demonstrate the ability to stream in real time, high definition, uncompressed 1080p video from a USB 3.0 hard drive and PC through our USB 3.0 IP on the HAPS platform and displayed via HDMI on a Samsung 1080p LCD TV.  Check it out http://www.synopsys.com/dw/ipdir.php?ds=dwc_usb_3

To try to be more clear,

A USB 3.0 Hard Drive provides the video to a PC with a USB 3.0 Host.

The PC is running a media player that plays the video.

The video is sent out through the USB 3.0 Host port to the FPGA board.  The FPGA board has the Synopsys USB 3.0 Device controller.  The Controller decodes the packets, sends them over to our HDMI Tx Controller, and out over an HDMI cable to the Monitor.

Even though Gervais Fong is our SuperPHY guy, we are using the TI USB 3.0 PHY (our friends in interoperability).

Thanks to Gervais, Dennis, and DisplayLink for this video.

USB 3.0 Video Blog – Episode 1

Posted by Eric Huang on January 28th, 2010

 

Here’s a short History of USB and a few USB 3.0 just shot this video in 2 takes, and used the first one because it’s less horrible than then second one.

The pictures I mention are actually in the previous Blog entry, that are below (somewhere).

I really hope this works.

Apple iPad has USB 2.0, not USB 3.0

Posted by Eric Huang on January 27th, 2010

As the LA Times reports, Steve Jobs announced the Apple iPad.  In addition, to WiFi, and Bluetooth, it includes a USB 2.0 port to connect to a Mac.  I really, really hope that you can connect this to a PC also with USB.  I assume this with use iTunes as the primary syncing tool, just as I do with my iTouch.

To the weirdos on the internet who would point out “There’s no USB 3.0!”  I would like to point out that this does not include USB 3.0 because this device has probably been in design for 2-3 years, probably before the USB 3.0 specification came into existence.  In other words, technology doesn’t appear out of thin air.

I also would like to point out that since the first version of the device has 64GB of Flash (most expensive option), next year’s will probably have 128GB, and the year after that 256GB.  This assumes that they follow the path of the first 3 generations of iTouch, the iPods, the Nanos, of which our family owns multiple versions of each.  I think the iPhone may have followed this path also, but I don’t own one of those.  Of course, I expect cell phones and media players from other leading companies will upgrade their memory capacity. 

Acer has been making big strides in the netbook area, and is introducing a eBook which isanother tablet.  Acer says that it will support Apps and run the Google Chrome OS.  In fact, Stan Shih throws down the gauntlet at the entire US PC industry including Apple and says the US PC brands will disappear like US TV brands. 

With so many products in this space, the tablet PC will be the perfect candidate for USB 3.0 for transferring content faster from a primary PC that downloads data from the internet regularly through an internet connection that is slower than WiFi or USB 3.0.

I’m going to go ask my significant other for permission to buy an iPad now.  Maybe if I buy two…
