    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

Double-Speed 10Gbps USB 3.0 Specs This Year, Products Next Year

Posted by Eric Huang on January 24th, 2013

1 MicroSD Card (or a USB Drive) holds this much data and even more

The USB-IF announced on “Double-Speed USB 3.0” on Sunday the doubling of USB 3.0 speeds

Key points:
1) Speed doubles to 10 Gbps
2) Backwards compatible to existing USB 3.0 software (no changes in software drivers)
3) Compatible with existing cables and connectors
4) Compatible with existing USB 3.0 hubs, devices, and USB 2.0 products.

You can guess pretty easily from this that the controllers and PHYs will need to change enough to support the protocol/electrical speed up, but keep backward software compatibility and electrical interoperability. This is NON-TRIVIAL.
The USB-IF will post the 0.70 Revision of the specs here for industry review starting February 7, ending March 26, 2013. http://www.usb.org/developers/USB-Futures.pdf

CNET Asia’s Crave reports Next Gen USB 3.0 products will hit the market in 2014. Read their article here http://asia.cnet.com/double-speed-usb-3-0-coming-in-2014-62219968.htm
You can read the USB-IF press release here talking about the Specification. http://www.usb.org/press/USB-IF_Press_Releases/SuperSpeed_10Gbps_USBIF_Final.pdf

The USB Implementers Forum (USB-IF) manages the USB specification development, conducts interoperability “plugfests”, creates compliance procedures, and enforces usage of the USB Logo. To earn the logo you need to pass a series of standard interoperability and electrical tests which help ensure interoperability with other products with the logo.

Why would I need Double USB 3.0 Speeds?

This is a great question that everyone is asking. Fortunately, over the holidays, Agent K provided me with an answer. Looking at the Image below, you’ll see 25 years of storage on lots of disks, doesn’t even add up to the one, little MicroSD card. (You could easily substitute a USB drive for the MicroSD Card since you know from reading previous blogs that they all use the same NAND flash memory)

I can’t even remember how much those 3.5 inch floppy disks held. (Comment below please)
My honest feeling is:
1) USB 3.0 is great
2) It works well
3) Storage needs are going up
4) USB 3.0 needs to speed up to keep up

Humor
Lots of funny things happened in the last 4 weeks. Few of which are appropriate for this Blog
1) I put a GoPro Hero2 Action Sports Camera on my head
2) I skied backwards
3) I skied backwards into a Large Metal Pole.
4) Fortunately, my head took most of the impact
5) My camera is fine.
6) Sadly, this isn’t as funny on camera. You see a very nicely framed video of someone skiing (in front of me, not me), then a camera falling into the snow.
7) My Ski Buddy asked “Is the Pole okay?”
