I’m constantly asked: "Will Thunderbolt replace USB 3.0?"

Thunderbolt and USB 3.0 will co-exist & live long, fruitful lives

As reported previously, Apple filed and recieved a patent for a new iPhone or iPad connector which looks  like a Thunderbolt connection. You can see in the picture that it includes connections for USB 3.0 and dual port Displayport.

Apple received the patent in April 2011.  Since it takes at least 3 years to get a patent, we can guess that Apple has known since at least 2008 (probably 2007), it would support USB 3.0.

Apple may or may not have had knowledge of Thunderbolt in 2007.  I can see a world (in 2007) where Apple knew it would want it’s iPad tablet to drive a bigger monitor through DisplayPort.  That could be the original reason for dual DisplayPort and not Thunderbolt.  I can only guess.

Where am I going with this?

1. Apple uses the PCs chips found in most PCs
2. Most PCs will move to Ivy Bridge
3. Ivy Bridge will be found in most PCs
4. Future Apple PCs will likely use Ivy Bridge
5. Ivy Bridge has USB 3.0
6. It’s highly likely Apple will support USB 3.0
7. Apple patents indicate they’ve planned all along to support USB 3.0

So if you are still with me, Apple will definitely support USB 3.0

Back to the question

Will Thunderbolt overtake USB 3.0?

Pros:

1. Faster than USB 3.0 today
2. Proven
3. On every Apple mobile PC

Cons:

1. Closed Standard restricts the ability to integrate.
2. Only one company provides discrete chips

The one way Thunderbolt could overtake USB 3.0 is if Thunderbolt opens up as a standard.

USB 3.0 will have more than 100 design starts for SoC integration

The USB-IF has something like 4000 members. By the end of this year, there will be about 200 different USB 3.0 Design starts.  Thats lots of people innovating products around USB.

Thunderbolt is closed.  It will stay closed.  This video explains why:

So the Innovator that designed Thunderbolt makes money from customers like Apple, Acer, and Lenovo that ship Thunderbolt.  Big piles of money.  People that need/want Thunderbolt pay for Thunderbolt.

The innovator promotes USB 3.0 for mainstream ease of use.  Consumers are happy.

Thunderbolt closed.  USB open.

Everyone is happy.

I dare you.

Apparently we’ve sold a bunch of DDR.

There was cake.

I ate 2 pieces.

I came across this Samsung tablet & smartphone chip with USB 3.0.  You can clearly see it has USB 3.0 as part of the design.

Even more fun, a Samsung says that this will go into a Samsung Galaxy 3 smart phone.  This means phones and tablets.

This makes the Samsung chip the 3rd tablet or smart phone chip that will definitely have USB 3.0.

TI OMAP is the first for tablets, and clearly goes into phones also.

The Ivy Bridge chip for PCs should go into tablets, but doesn’t appear to be made for phones.

And the Samsung Exynos 5 chip which looks like a tablet and phone chip.

Realizations

I had lunch with my Mom and Dad Sunday. 

I told them about a video I planning to record.

The videos will be recorded by our most excellent marketing team of Darcy Hickey-Pierce and Hannah Watanabe of Conversation Central. (As usual do not click on that link stay here because you may not come back).

Back to the Video: My Mom and Dad both gave advice on how to put the proper market messaging in my video.

At this point, I realized, my Mom has never read my blog or watched my videos.

Which means I’m the only one who reads it.

Great.

Just Great.

Remember Mother’s Day is May 12th in the U.S. 

Celebrate and send your mother a link to this blog.

Maybe your Mom will read this blog.

My Mom does not.

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.

Here’s the longer, more detailed version of our USB 3.0 SSIC demonstration.   It’s 7 minutes.  It’s going to be the best 7 minutes of your day.

SuperSpeed Interchip Proof of Concept–Long Version

If you want to watch the shorter version (or more of a description) go back to last week’s blog here for a written description of the SuperSpeed USB 3.0 Interchip (SSIC) demo.

I meant to post it Thursday last week, but apparently I lied.

Last week I wrote “…someone pointed out to me that no one is going to ever watch these videos twice.”

I received this comment in response, “Eric you are right, I’m never going to watch theses videos twice”

Thanks.

Thanks very, very much.

Synopsys worked with the USB-IF SSIC Working Group to develop a SSIC Proof of Concept demonstration. 

The USB-IF has been working on SSIC for some time.

This Proof of Concept in FPGA is to test the SSIC specification version 0.90 to see if it actually works in hardware.

It worked (mostly).

We learned, as expected, the SSIC Spec needs changes.

We learned what works and fixes need to be made to the specification.

We used our own HAPS FPGA platforms and standard PCs.  The HAPS51-2s are connected to the PCs with PCIe.  The FPGA boards are shown below.

On top (left side of table) we have a modified USB 3.0 Host for SSIC.

On bottom (right side of table) we have a modified USB 3.0 Device for SSIC.

There is no USB 3.0 PHY in this set up.  Read to end for more on the PHY used.

Take note:  FPGA-Based Prototyping is a good idea as part of specification development too.

As with our standard USB 3.0 Host and Device, we could close timing in the FPGAs at 125MHz even when the FPGA design is over 80% utilized.

We’ve edited 2 versions the SSIC Proof of Concept video for your viewing pleasure. 

A short version and a long version.

The short version focuses on the hardware setup and the demonstration.  It’s posted below.

SSIC Proof of Concept – Short Version

This is Shailesh and I just before we started the demo.

What is the point?

The SSIC USB-IF WG has both proven the SSIC concept works, and improved it using FPGA-based prototyping.  The USB 3.0 can be used with the SSIC modifications to use USB 3.0 on PCB for chip-to-chip communication with less power than USB 3.0 outside the box.  It preserves software so you continue to use existing USB 3.0 drivers and stacks.

What is SSIC?

See the previous entry here for a brief description.

It will be used to connect Applications Processor chips to other USB 3.0 peripherals inside the box, on PCB.  It is a chip-to-chip protocol. 

For example, it could be used to connect a Mobile Apps Processer to a WiFi baseband chip.  The Apps processor could use the same, unmodified USB drivers it uses for an external, USB plug in WiFi modem.   It uses USB 3.0 to communicate, but it can less power because it drives signals over a few centimeters of PCB, not 3 meters of USB 3.0 Cable.  SSIC uses a different M-PHY for SSIC.   It uses less power.  We don’t use an M-PHY in the SSIC Proof of Concept.

 

Caveat and Disclaimer

This is not a product and this is not a product announcement.  This is a working demonstration of the technology.

Read to the End

The long version is 7 minutes and has a lot of detail and is only for the most brave USB viewers.   It has a more detail detail on how the two boards are connected.  So I lied.  There is no detail how the two platforms are connected when the USB 3.0 PHY is not used. You have to wait until Thursday and watch that video.

See you Thursday.

I wanted to post the short video first and post the long video later, but someone pointed out to me that no one is going to ever watch these videos twice.

So I separated them anyways because you were going to come back on Thursday anyway.

Tomorrow, I should be posting something of interest to you on SuperSpeed Interchip (SSIC).

If all goes well.

SuperSpeed Interchip (SSIC) brings USB 3.0 from outside the PC to on the PCB to use USB 3.0 between chips.  It allows you to reuse your USB 3.0 software drivers and take advantage of USB 3.0 gigabit speeds to communicate between chips on the circuit board. 

More tomorrow.  Most likely.

Yes, this is a terrible blog entry.

I like Fried Dumplings, Steamed Dumpling are good also.

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 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.

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.

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.
