    Covering the latest trends and topics in USB IP.

    I started working on USB 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

TI OMAP 5 for Phones & Tablets with USB 3.0

Posted by Eric Huang on 27th July 2011

Here’s a TI promotional video for their upcoming TI OMAP.  I highly recommend you take a look at the entire video.

Texas Instruments OMAP 5 by <a href=http://www.dailymotion.com/GPSAndCo


You will see it features:

    1. Gesture Control

    2. PicoProjector – The best use I’ve seen of one so far.

    3. eWallet

    4. Augmented Reality

    These applications require throughput.

    If you look at the diagram here at TI.com, you can see 2 interesting things:
    1) USB 3.0 &
    2) MIPI CSI with 4 ports

    image

    • This chip will be in a Mobile Phone or Tablet
    • That Phone/Tablet will have 128GB+ of Flash Memory, you need USB 3.0 speeds to move video, pictures, and data on and off Phone/Tablet quickly.
    • The 4 MIPI CSI connections, mean 2 forward and 2 backward facing cameras.
      • 2 Cameras forward =
        • HD Still Capture
        • Probably 3D Video Capture
      • 2 Cameras backward
        • 3D Video Capture for accurate gesture/motion recognition
        • Maybe 3D Video Conferencing

    The TI demo shows the phone used for everything.

    Microsoft Store, Windows 7 Phone & Tablet PC Reviews

    Posted by Eric Huang on 14th July 2011

    So that I don’t have to re-name this blog “To Apple or Not to Apple.” Here’s my really surprisingly, super positive experience at the Microsoft Store in the Mall of America.  

    USB 3.0 in Laptops

    After being grNeda holding up Windows 7 Phone at Microsoft Storeeeted by several people, in brightly colored T-Shirts, I asked a one person, “Where are the USB 3.0 PCs?”  The Microsoft Genius, Neda (pictured right).

    Neda immediately rattled off about 4 laptop PCs that had USB 3.0, including 2 Sony’s and 2 Dell’s.  She told me that you could identify the USB 3.0 ports as “blue” except for one that was “black” but labeled as SS.  Then, Neda showed me the models and the ports.  Neda also told me that the most of the new.

    Windows 7 Phone

    I asked about the Windows Phone, and she said, “Oh yes, the WIndows 7 Phone?  Right over here.  She showed up and demonstrated 4 models, 3 were HTC, and the one she’s holding up is the first model available on Verizon.

    I’d like to note that the “tiles” (really just big icons, visible on the phone above) responded quickly to the touch, and switching between screens was quite fast.  I might even say transitions were faster than on the iPad 2 or iPod Touch 4.

    Market Observation, I’m making some assumptions here, but if the APIs are the same for Win 7 Phone and Win 7 PC, it will be easy to move apps from PC to Phone.  This really could put Microsoft in the running as a serious competitor for the smart phone space.

    Windows 7 Tablets

    Neda then demonstrated 3 tablets in the Store, each improving on the other.  Here’s my Slate and Tablet Reviews in 1-3 sentences.

     ASUS Eee EP121 Slate

    ASUS Eee EP121 Slate with Gorilla Glass

    The first high-end, ASUS Eee EP121 unit had Gorilla Glass, “Tougher than the other models, and more of a desktop replacement,” said Neda.  WIth the free case, wireless keyboard, and 3 year protection plan it’s priced at ~$1300.  It has an HDMI port and SD card reader (missing from the iPad 2).  More here at Amazon where it gets 4 out of 5 stars after 120 reviews.

    The touch screen seemed highly responsive and navigating Win 7 was easy.  It uses an i5 Processor, same as in most laptops today.

     

     

    EXOPC Slate

     

    EXOPC Slate

    The EXOPC Slate has only 1 review on Amazon.  It doesn’t have the gorilla glass. It retails for $700 with a <4 hour battery life.  I wish I had more to say on this one, I realized I didn’t check the responsiveness of the touch screen or even play with it as I focused on the other 2 models.

     

     

     

     

    Acer Iconia W500 Tablet with Docking Station

    Acer Iconia W500 Tablet

    The Acer Iconia W500 Table retails for  $550 at the Microsoft store. At Amazon it gets 4 out of 5 stars from 129 reviews.  If you look carefully, at this picture it has USB 2.0 based docking station.

    The docking station includes a USB 2.0 keyboard, ethernet port, and additional host ports.  This means it has an embedded USB 2.0 Hub and possibly a USB to ethernet controller chip also.  The tablet has it’s own power cord

    Acer Iconia W500 Docking Station USB closeup

    You can see a close up of the USB connector to the right.  Neda explained that the 2 round metal pieces on either side are for stability.  Power still flows from the tablet to this USB docking station using the USB connector, as far as I can tell.

    The tablet is about 2.1 lbs and has a battery life of <6 hours.  The iPad 2 at low brightness is probably more than 6 hours.  But, this is a Win 7machine, and the touch screen was quite responsive, and windows popped up quickly.

    My conclusion is that these are serious contenders from a performance point of view.  In terms of ease of use, like needing to re-format the SSD every year is questionable, but if Microsoft and the hardware vendors can make these as easy to maintain as the iProducts, the performance and range of applications will make these systems viable alternatives to the iPad (especially the last unit at $550).

    I definitely recommend you take a look at a Microsoft Store next time you visit a mall.  You might learn something and see something new.
