Archive for the 'USB 3.0 Adoption' Category

PC Chipsets with integrated USB 3.0 (from the Innovator/inventor of USB) started shipping at the beginning of April for reviews.

Here’s a table from Anandtech clearly showing there will be 4 USB 3.0 ports!

They’ve added 4 USB 3.0 ports and to the existing 14 USB 2.0 ports.

If you look at your laptop or desktop, you won’t see that many USB 2.0 ports on the outside because some are used internally.  They connect to a 3G modem or a card reader or ExpressCard slot.

ASUS, HP, Samsung, Toshiba, and others have already announced they will have laptops based on the Ivy Bridge chipset, just Google Ivy Bridge PC and you’ll get all the models

It turns out that AMD has been shipping a motherboard also.

I found this article comparing the performance of the Ivy Bridge and AMD integrated chipsets against NEC, VIA, and ASMedia USB 3.0 Host controllers at http://techreport.com/discussions.x/22775.

Here’s part of the Graphs from that Report.

  From http://techreport.com/discussions.x/22775

As expected, the Ivy Bridge Chipset performs faster, it’s the Blue bar.

I’m going to make you go to the actual article at techreport.com to see what the other chips and integrated chips sets are on the graph because I think the website deserve the hits.

Integrated is Faster

Ivy Bridge is faster because it’s fully integrated:

The stand alone chips used in the NEC, VIA, and ASMedia Hosts can NOT achieve faster speeds because they are limited by their PCIe Gen 1 x1 connection to the motherboard.   PCIe Gen 1 x1 can only go up to 2.5 Gbps, and it’s less in a system where many PCIe peripherals are using the PCIe bus.  Ivy Bridge shouldn’t suffer from this because it is fully integrated into Ivy Bridge and probably has at least a PCIe Gen 1 x2, x4, or even x16 to make sure there is plenty of bandwidth to move the USB 3.0 data in and out of the system. 

For detail on factors that reduce or increase USB 3.0 performance read this blog entry.

I’m going to make you go to the actual article at techreport.com to see what the other chips and integrated chips sets are on the graph because I think the website deserve the hits.

Why the performance isn’t even faster (maybe)

Performance Note: the report does NOT tell us what kind of USB 3.0 Drive they used for testing. I can actually guess which Flash Drive they are using based on the max read speeds that I see, but that will be for a later blog entry.

I think the throughput is limited by the speed of the actual USB 3.0 Hard Drive or USB 3.0 Flash drive being used.

1. If it’s a USB 3.0 Hard Drive, it probably uses a bridge chip from USB 3.0 to a SATA 3 Gigabit/second (Gb/s). This means the maximum Read speed would be near 300 MegaBytes per second (MB/s) or about 3 Gb/s. 
2. If it’s a USB 3.0 Flash Drive, it’s speed will be limited by the quality of the Flash inside the drive.  The fastest flash speeds we’ve ever seen is about 300 Mb/s with a $600 SuperTalent flash drive that arranged 2 banks of flash in a RAID configuration.   At $600, this isn’t a really a consumer product.

   Basically, it was fast because it used the fastest Flash memory, lot of it (128GB), and arranged it in two pieces for simultaneous access to both pieces.  I don’t consider this to be a commercial product, and it didn’t sell that many because it cost more than a Hard Drive, but it gives us an idea of what performance is possible with Flash Memory.

USB 3.0 in Tablets

Apparently Ivy Bridge is also targeted at Tablet PCs with Win 8.   This makes Ivy Bridge the second chipset with integrated support along with TI’s OMAP 5 demonstrated at CES 2012 in January.

This confirms Rahman Ismail’s comments (USB-IF CTO) correctly stated USB 3.0 in tablets and smart phones will be appearing in 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.

For all the details on USB Compliance (and this is really for your USB engineers) go to http://compliance.usb.org/

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.

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.

The Writer of this Blog, Me

Forced by our Social Media Experts to do this “Meet the Blogger” video or Synopsys would suspend my yearly allotment of donuts.

Here’s the video.

To USB or Not To USB Blogger Eric Huang

The makeup and hair for this video shoot was unnecessarily time consuming.

Last Chance of the Fastest USB 3.0 Flash Drive

You guys aren’t even close to guessing. Comment below.  Maybe the winner will get a USB 3.0 Flash Drive.

Answer key next week.

Rate this Blog Entry.

Remember 5 stars is the best rating, 1 star is the worst. (So I’m sure the 1 star rating a few weeks ago was a misunderstanding)

Comment on the blog or e-mail me (you know who you are) on what you like or don’t like.

I get e-mails for most entries now so I appreciate those comments and input.  Thank you for reading.  If you get this far, e-mail me the word “donut” and I’ll buy you a donut next time I see you.

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?

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:

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.

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.

Because you read this blog, you already know that DisplayLink has taped-out a chip and started a second chip from our press release in October 2011.

DisplayLink makes a USB 3.0 to HDMI or DVI converter.

If you clicked on that image above, and nothing happened, it’s because it’s not a hyperlink, it’s just a picture.

The Video is below.

Here’s DisplayLink’s Theo Goguely talking about their product using the Synopsys USB 3.0 Device IP, USB 3.0 PHY IP, and HDMI Tx IP.

Here’s the 2 products that DisplayLink’s Theo Goguely demonstrated.

DisplayLink customer product #1: The IOData USB 3.0 to HDMI/DVI adapter using the DisplayLink chip.  Shown below.

DisplayLink customer product #2: And the Targus USB 3.0 Docking Station which you can buy at Office Depot, or just Google “Targus USB 3.0 Docking Station”

This Docking station includes a USB 3.0 Hub, and the DisplayLink chip downstream to provide the 2 video outputs.

In addition, DisplayLink customer product #3: The HIS USB 3.0 to HDMI adapter Here’s a 3rd USB 3.0 product that I found on the DisplayLink website.

Here’s where you can buy the HIS USB 3.0 to HDMI video adapter on NewEgg

Words will never hurt me.

Unless they are mean words.

HP’s all in one TouchSmart 520 PC has 2 USB 3.0 Ports included in a beautiful, single unit touchscreen PC.

It has a BluRay burner, which is pretty cool too.  So HP beats Apple in features here. Read the PCWorld Review article here.

ADATA now waterproofed USB drives, so you can carry these around when you go scuba diving or stir your coffee with them.

You should note that the top speeds of these USB 3.0 drivers is 100 MB per second.

Top USB 2.0 speeds are 35 MB per second. Top USB 3.0 speeds are 350MB per second.

The ADATA speed is still 3x the speed of USB 2.0 which is definitely faster.  The speed limiting factor is actually the flash memory. It uses memory more expensive than memory found in today’s USB 2.0 drives, but still slower than needed to get the fastest USB 3.0 speeds.  Just keep this in mind.

The Kindle & USB – Viewer Mail

Ned writes in “"Interesting blog about the Kindle Fire and iPad.  I can’t, however, figure out what it has to do with USB…”

(Ned isn’t his real name.)

I’m glad you asked this question Ned.

This Tablet, the Kindle has only one wired interface, it’s USB 2.0.  It’s used for both charging and for content transfer.

For example, If you keep your music in the “Amazon Cloud” you can download via WiFi.

But, most people (I think) already have their entire MP3 library on a USB hard drive or a PC or both somewhere.

So it’s a lot faster to plug your Kindle Fire into a laptop or PC, and transfer all your Britney Spears and Rihanna music to your device.

You could upload your music to the Amazon Cloud, or even the Apple iCloud.  You’d then have access anywhere. And you could stream to your device.

Of course you need Wi-Fi or Broadband access to download these items.  So you still want to download with USB 2.0.

Why do you care?

Well, you’ll still need to charge your device now and in 2014.

And you’ll have even more content.

And you might not be willing to pay for a huge “cloud” to store all your data.

Are you going to trust all your kid’s photos to a single, on-line storage facility at Amazon or Apple?

Will you pay $500 a year for the storage, when a USB 3.0 drive costs only $100?

No.

You buy 2 USB 3.0 hard drives. You store your stuff there, and keep a small amount on the cloud.

So you will have USB 2.0 now and USB 3.0 soon on all your tablets and smart phones so you can keep carrying around a gazillion videos you recorded, pictures you took, and movies/TV shows you want to watch.

Kindle Fire TechRepublic Teardown

Here’s a picture from the TechRepublic teardown of the Kindle Fire.

It’s interesting to me because the RAM chip is mounted directly on top of the TI OMAP 4430 chip underneath.  As a digital guy I don’t know why someone does this, except to improve performance, and maybe lower power required.  Someone send me an e-mail to explain why or post a comment below.

You will see the TI OMAP 4430 actually appears to have 2 USB controllers.

One is an HSOTG port on the top right.

The other is in the bottom left, and looks like a USB 2.0 Host controller.

The new OMAP 5 platform as has 1 USB DRD port and 3 USB 3.0 ports. Block diagram and description can be seen here in my earlier blog entry on OMAP 5 and Tablets.

So TI’s already moving the next platform onto USB 3.0, so in 2 years we would see TI OMAP tablets with USB 3.0.

Eric’s Kindle Fire

I opened my Kindle Fire today (upon returning from Asia).
I’m pleased but underwhelmed.

First Impressions:

1) Great Screen
2) Heavier than Kindle 3rd Generation, much heavier than iPod
3) Fast Browsing
4) Interface as responsive as the iPad
5) I have no content (except for lots of books with talking animals in those books).

But, I can stream video from Amazon Prime, so that is a bonus. I can now cancel my Netflix account completely after 4 years, despite a tiny selection of streaming videos.

I can also borrow 1 book a month from Amazon’s lending library as long as I pay for Amazon Prime.

Still it isn’t an iPad, or an iPod or an iPhone.

For $200 it’s a great deal for anyone looking for a tablet for e-mail and light surfing and buying lots of stuff on Amazon.

It has a larger screen than the iPod at $200, but you won’t go running with a Kindle Fire strapped to your arm either. 

One thing the Kindle Fire does not do is Text-To-Speech.  So, I guess Amazon doesn’t really love me. (Yes I’m still mining original Kindle review because it’s the one people have most commented on or e-mailed me about.) You can read how free donuts go together with Kindles here.

Formatting blogs – We switched our website around. We were continually getting hacked.  I have no idea why anyone would hack my lousy blog.  So the formatting on this might really be bad.  If so, I apologize, and applaud your efforts as you read down this page.

International Flights – Kindles and iPads

I noticed lots and lots of people with either Kindles or iPads.  I noticed more people reading on their iPads than I normally do.

I sat next a some poor CEO who got stuck in a middle seat in economy with people like me sitting on the aisle.  She said, "This is going to sound stupid, but I mostly read on my iPad." "I don’t play games," she said.

So I guess the KindleFire gets the Amazon crowd to upgrade to a color screen (and staying up  all night reading because of the active light source keeping their brains awake).

Amazon also grabs the people that stood outside HP (next door to us) to get a TouchPad who actually didn’t stand outside, but want a supported product.

My point is: Apparently, a lot of people read, and they like to read, but this Tablet extends the reach to other people who don’t read, but want a nifty, cheap tablet. (It’s possible that reading and wanting a nifty tablet are not mutually exclusive as well)

Yes, I know, if you’ve followed the Kindle Fire launch at all this isn’t new.  I have to say, I’m a bit underwhelmed at the moment, but after I transfer some legal video content from my Tivo to my Kindle Fire, I might feel better.

(Late Note: I found that I have a digital copy of “The Dark Knight” in the Amazon Cloud, so I’m listening to that while I finish this entry. In just 5 seconds it had enough downloaded to start playing the movie).

The thing that I like about the iPad 2, is that when I buy a video or app, it automatically downloads to my desktop, and I can sync the content with all my other devices quickly.  I can’t do that with my Kindle, and I’m not planning on re-buying content, so I might end up buying another iPad rather than 2 more Kindles.  I don’t know yet.

40+ Designs, 30+ Customers for USB 3.0 digital IP and PHYs

I’m really proud of our R&D and Support teams who built and supported tape-outs of real products in real chips at real customers like DisplayLink and Realtek.

I should point out the 40+ design wins are for actual ASICs that have already started, or have finished, and not just FPGA prototypes.  Corporate strictly regulates formal announcements, so we provide the most accurate data we have. We count real USB 3.0 products.

Here’s a video from DisplayLink explaining why they buy IP from suppliers that have lots of customers.
