    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

IP Summit with USB 3.0 IP, Blooper

Posted by Eric Huang on March 15th, 2012

 

We’re having an IP Summit  March 28 in Santa Clara.  As with all our seminars, it’s based on visiting 100s of customers a year.

Topics Include:

  • Analog and Physical IP
  • PCIe
  • Embedded Memories (Embedded Test and Repair)
  • Audio IP
  • Non-volatile memory (NVM)
  • DDR
  • USB 3.0 on HAPS – or USB 3.0 – Ready, Set, Integrate

 

The USB 3.0 one is extremely practical.

I highly recommend it for anyone considering using HAPS for FPGA prototyping OR anyone building USB 3.0 on an FPGA platform.  We go over USB 3.0, HAPS FPGA prototyping, and specific steps for integrating USB 3.0 into FPGA.

How do I know it will be useful?

All our 40+ USB 3.0 customers have needed some or all of this information.  So we developed this training. 

If you use our USB 3.0 it will be useful.

If you don’t use our USB 3.0 it will be useful.

Send your junior engineers

Send your senior engineers.

Send yourself so you can look smart when you tell your junior engineers and senior engineers what to do.

 

Look at the entire IP Summit agenda here (http://www.synopsys.com/IP/Pages/IPSummit2012.aspx).

Register. Attend.

 

Do it.

 

Do it now.

 

Please.

 

 

Blooper

In exchange for 150 views of our Japan IP R&D Team Video, I promised a blooper video.

We are now at over 325 hits making it one of the most viewed

Here’s our Behind the Scenes video.

Fastest USB 3.0 IP in the Universe

Posted by Eric Huang on March 12th, 2012

Here you will see demonstrated the fastest USB 3.0 IP in the Universe*.  Or at least the fastest published numbers that isn’t marketing hype.

This demo shows SuperSpeed USB 3.0 effective throughput:

  1. SuperSpeed USB 3.0 can really move data.
  2. Synopsys USB 3.0 IP can really move data.

The demonstration includes our USB 3.0 xHCI Host Controller, USB 3.0 Device Controller, and USB 3.0 PHYs.

You have to actually watch the video to get see the effective throughput.

The Fastest USB 3.0 IP in the Universe

First, I have to say that that is about the most awesome thumbnail picture of me yet.  Thank you YouTube!

Second, we optimized the PC systems as follows:

  1. RAM Drive on the Mass Storage Device side – This is a lot faster than a flash drive, an HDD, or an SSD.  There’s no SATA or PCIe for the data to pass through, so there is zero latency from an additional protocol.  The RAM is right next to the USB controller so there is basically zero read/write latency.
  2. Windows 7 with an MCCI USB 3.0 xHCI Host Stack – Somehow MCCI engineered this so it’s faster than stacks we’ve seen packed with off-the-shelf Host cards.
  3. Nothing else is running on the USB bus or PCIe bus on the PC.  Very little is running on the PC.
  4. Standard PCs built with standard parts with SSDs (which aren’t really necessary but we wanted to make sure)
  5. Our IP – Our USB 3.0 PHY IP, Our USB 3.0 Host IP, and Our USB 3.0 Device IP.

Okay, if you know a demo that is faster, send me the link or post the link below.  I haven’t seen a faster demo using a standard benchmarking tool.

Remember

Synopsys USB 3.0 IP can move data really, really fast.

 

Blooper Video

Somehow that Japan IP Team video hit over 330 hits as of the writing of this blog.

I will post it Thursday U.S. Time.

Probably.

*It might not be the fastest USB 3.0 demonstration in the universe.  The title was to get your attention. Still try and find a demo, a real demo that is faster.

**A limit of 10 donuts will be given out.  Offer void where prohibited by law. (This means this offer is no good if it’s illegal where you are. I don’t know why it would be illegal.  Maybe the local authorities don’t like donuts.)

Synopsys USB 3.0 Host Certification Demo with USB Gold Tree

Posted by Eric Huang on February 27th, 2012

Most people don’t have a clue what goes on with USB 3.0 Certification (or USB 2.0 Certification).

So here’s a video of our USB 3.0 xHCI Host interoperating with a whole bunch of USB products.    These products are arranged into a USB Gold Tree as specified by the USB-IF.

 

USB 3.0 xHCI Host Certification Test–USB 3.0 Interoperability with USB Gold Tree

 

We use the MCCI USB 3.0 xHCI Host Stack running on Windows 7.

To my knowledge, this is the only time anyone’s ever been crazy enough to post a video demonstration of the USB Gold Tree.

You can see you need to work with USB 3.0, USB 2.0, and USB 1.1 Devices.

The USB 3.0 Gold Tree uses

  • USB 3.0 Hub and USB 3.0 Flash Drive for Super Speed Bulk In and Out Transfers
  • Four USB 2.0 Hubs
  • Two USB 2.0 Web Cams for Hi-Speed USB 2.0 Isochronous Transfers and Interrupt Transfers
  • USB 2.0/1.1 USB Headset with Microphone for USB 2.0/1.1 Isochronous Transfers
  • Two USB 2.0 Flash Drives for Hi-Speed USB 2.0 Bulk In and Out Transfers
  • Keyboards and Mice for Low Speed USB 1.1 Interrupt Transfers
  • And not visible underneath is a USB 2.0 Printer for more Bulk Out Transfers and Interrupt Transfers.

In this way, it’s possible to test for all the different types of USB traffic.

 

The USB 3.0 xHCI Host is implemented on our HAPS FPGA-Based Prototyping Platform with our Synopsys USB 3.0 PHY.

Duty Free USB 3.0 –at the Japan Airport, To USB or Not To USB, Analog Insights, MIPI OnTheGo

Posted by Eric Huang on February 17th, 2012

If you can buy something in the airport, it’s mainstream product, right?   This Duty Free USB 3 Hard Drive sells for 147,000 Yen at Narita Airport.

 

IMG-20120128-00494

 

I like saying “Duty Free USB 3.” It rhymes.

The 147,000 Yen price = 189 dollars.  A little pricey, maybe because every imported electronics device into Japan carries a heavy premium.  It’s about $120 at Amazon or most on-line stores.  At Everything USB review of the Elecom rikiki USB 3.0 Hard Drive puts it in number 2 out of 4 tested units range of performance for a “bus powered” USB 3.0 drive.

USB Factoid

Bus powered USB = Uses power provided by USB port on your PC.  You don’t need an extra cable just for the power adapter.   All Flash drives work this way and some hard drives

Self-powered USB = You need both a USB cable and a power cable.  For example, all USB Printers require both a power cable and a USB cable.

(Yes I know a lot of printers use WiFi and never use USB. )

 

My point is: You can buy this USB 3.0 drive in the airport.

 

Other Synopsys Blogs – Analog Insights and MIPI OnTheGo

I’m reluctant to recommend other blogs at Synopsys because:

  1. They are well written and useful
  2. If I refer you to them, they may get more blog hits than me.

Here are 3 (more) blogs to check out.

  1. Our recently revived “Analog Insights” blog has a new blog author HĂ©lène ThibiĂ©roz.   She writes practical blog entries including the most recent “10 tips to improve performance using HSPICE.” 
  2. Our MIPI Product Marketing Manager Hezi Saar writes about mobile standards in “On The Move”.  Take a look at Hezi Saar’s entry on USB 3.0 SSIC using the the MIPI M-PHY
  3. I’ve recommended Navraj Nandra’s “The Eyes Have It” before.  His most recent entries relate to 28nm process nodes and beyond.

 

(After you’ve sampled those blogs, come back)

 

Back to me.

USB saves the Earth

Posted by Eric Huang on February 13th, 2012

So the European Union has said, you must use USB as the charger for all cell phones in Europe going forward.  In fact, the EU estimates that there are over 1 Billion non-USB chargers sitting around Europe that are simply garbage.  By changing over to USB as the standard connector, this will eliminate the need to destroy or dispose billions of non-USB chargers.

It’s likely then you won’t get a charger in the box of your new mobile phone within the next 3 years.  Every phone maker will assume you have 3 in a drawer somewhere.

These (fun) videos from the EU explain why.  Who would have thought the EU could be so much fun?

Dinner Party and EU Common Phone Charger using USB Power

I’ll have a new blog on Thursday (or Friday) with referrals to 3 other blogs.  I expect that you will come back to my blog 2x for each click you give them.

TI OMAP 5 Demo – First Mobile / Tablet Reference Design with USB 3.0 fully integrated, The Faster USB 3.0 Flash Drive

Posted by Eric Huang on February 5th, 2012

TI has now demonstrated the TI OMAP 5 chip which fully integrates USB 3.0,

It would have been even better for us SuperSpeed USB freaks if TI had actually demonstrated the USB 3.0 portion.

Instead, TI demonstrates stuff like 64fps 1080p video, highly responsive touchscreen scrolling, and points to all the interfaces.

Engadget’s exclusive pictures of the TI OMAP 5 Software Development show micro-B USB 3.0 connector there below the volume controller rocker switch.

image

Image Source: Engadget

Below the longer USB 3.0 micro-B connecter, you will see the mini HDMI connector called MHL which looks exactly like an old USB 2.0 mini-B connector because it is.  It was stolen by the HDMI group for use in portable designs.

(We didn’t want the mini-B anyways, when the USB-IF developed the micro-B that was clearly better so we are happy to have HDMI take old standards for their nefarious purposes)

As far as I know this the TI OMAP 5 Software Development Kit about first evidence of USB 3.0 in mobile phone, table, ultrabook design yet.

According to Anandtech

“The first devices based on OMAP 5 aren’t expected to ship until early 2013, with some aggressive customers potentially shipping at the very end of this year.” –Source: Anandtech

Well, I hope to see that out the OMAP 5 platform deploy with USB 3.0 in a real product in 2012. Which would back up with Ismail Rahman said about USB 3.0 appearing in mobile phones and tablets in 2012.  I warn you not to click on that last link to my blog entry.  Someone gave it one star.

 

You can read more at Engadget about the OMAP 5 demo at CES 2012 to read more, or you can watch the embedded video embedded below.  Engadget has an HD version of the same video at that link.

A Faster USB 3.0 Flash Drive?

I received an e-mail saying my blog “Fastest USB 3.0 Flash Drive?…” might not be super-duper inaccurate.

I asked for samples for lab testing, I’m waiting for a response.   Next blog entry, I’ll write about this flash drive.  If you can find it, comment below.  (It’s already publically announced).  My thanks to the commenter for pointing this out.

The Fastest USB 3.0 Flash Drive? from Sony

Posted by Eric Huang on January 19th, 2012

Sony built the fastest USB 3.0 Flash Drive (that I know of) to date.

 

 

 

I actually have to measure this myself, but the stated numbers from Sony’s website are

60 MB/s for the 8 GB drive and

120MB/s for the 16/32/64GB drives.

Our fastest USB 3.0 Flash drive in the lab is the Super Talent which runs at about 74 MB/s for the 16 GB version.

This makes the Sony Drive about 60% faster than the Super Talent.

 

Caveats to this after this table from Sony’s website below:

image

 

Caveats – The first and fastest USB 3.0 Flash Drive was actually a SuperTalent drive at 128GB.  It was a raid drive, so it had at least 2 banks of memory to allow for faster, reads from the drive. This wasn’t a mass market drive. It cost $600 for one drive.  The SuperTalent 16GB drive is $20.  The Sony will probably be in the same price range.

So for the moment, I’m guessing that the Sony Micro Vault will be the best performing USB 3.0 Flash Drive for consumers for awhile.  I’m also guessing it uses more expensive flash memory for faster access, it probably also uses a raid type configuration as well for faster performance for the larger capacities of 16GB and more.  I’m just guessing.

USB 3.0 hits Smart Phones & Tablets in 2012, (Yes 2012)

Posted by Eric Huang on January 11th, 2012

Happy New Year!

Yes, it’s still Happy.

My understanding: The world won’t end in 2012.

Which is great because according to the Ismail Rahman, CTO of the USB-IF says, that Mobile Phones and Tablets will support USB 3.0 in 2012 (PC World USB 3.0 in Smart Phones and Tablets article) 

Smartphones and tablets will also recharge faster through USB 3.0, as the power will flow faster than in USB 2.0, says Rahman

This is because a USB 3.0 Host port will provide up to 900mA of power for charging, which is more than the 500mA supplied by USB 2.0.  So he’s correct.

One thing PC World asks/says/challenges Ismail on:

But transferring data using the current USB 3.0 technology at such high data rates requires more power, which does not fit the profile of mobile devices.

Ismail responds:

“It’s not the failure of USB per se, it’s just that in tablets they are not looking to put the biggest, fastest things inside a tablet,” Ismail said.

He’s correct.  Another awesome response I might give is:

“Actually, USB 3.0 is more power efficient.  It transmits then shuts down.  USB 2.0 has a Host transmitting all the time with every device receiving signals all the time.

Also, at 10x the speed for only about 2x the power (in general) in means that a 10 minute transaction only 1 minute.  Then it turns off.  So it’s off for 9 minutes for USB 3.0 compared to USB 2.0.  So the power consumption is only 20% of USB 2.0.  So the battery lasts longer, about 5x longer just for the transfers…  USB 3.0 is better out of the box.”

There are some conditions, some secrets to the design at the system level to make sure this happen.  Basically, you need to be able to suspend the power to as much of the USB 3.0 elements as possible or shut down the power completely.

So Rahman points out USB 3.0 is coming to Tablets and Smart Phones in 2012, and theoretically he’s got some product knowledge as the CTO of the USB-IF.  I’m wondering if this is the TI OMAP 5 platform as announced by TI or something else?

USB at Home

You can install USB outlets at home for a mere $25.  Each port provides a full 1mA of charging which is good for charging your iPad or Kindle or Android phone, or BlackBerry or maybe your digital camera or cell phone. Got to FastMac.com for more info.   I know I could use them.

USB-IF Certifies PC Chipsets–The ones you care about

Posted by Eric Huang on December 12th, 2011

 

So it’s happened, the company the company that invested USB, and drove USB 2.0 and now USB 3.0 to success has certified their own USB 3.0 Host Controllers.  The USB-IF announcement image (and hyperlink) is below.

 

 

Intel PC Chipsets receive USB 3.0 Certification

It looks like the Series 7 chips set goes into standard PCs that you and I will buy, so mostly laptops and desktops.  The C216 series appears to be for servers.

A link to the press release is here: http://www.usb.org/press/USB-IF_PantherPoint_FINAL.pdf.

 

AMD’s Certified PC Chipset – Where is it?

This follows AMD’s press release from back in April 2011 of a certified chipset.  We haven’t seen either in mass production, but we might guess that both will time their releases to coincide with wide scale Windows support.

 

Windows 8 with USB 3.0

Combined with the Microsoft Windows 8 announcement and demonstration of USB 3.0, Intel’s announcement means we are on the path to 1 Billions USB 3.0 enabled products in 2 years as consumers look to attach something to these speedy SuperSpeed USB 3.0 ports.
