    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

BluLightning Form Factor & USB 3.0 in a Digital Camera or DVC

Posted by Eric Huang on 25th August 2010

BluLighting Cards & USB 3.0 – The BluLighting card uses standard USB 3.0 receptacles.  These are the same receptacles that you will find on your Mobile phone or digital camera.BluLightning Card showing USB 3.0 recepticales

For the Consumer, This reuse allows you to use standard USB 3.0 cables to connect to the card to your laptop.  No special card reader is needed.  The same cable you use to connect your camera or phone to your PC will let you connect to the card.

For the Manufacturer, standard receptacles mean you can get cheaper USB 3.0 connectors that are produced with high quality in high volume.  Again, you get to reuse USB controllers, software, IP.

For the PC Maker, they can (potentially) have one less slot on the PC, like an SD slot, or at least you need to add a new slot for a new form factor.  (More on this in a later blog post)

 

BluLightning in DSCs and DVCs

Future digital cameras (DSCs) or digital video camera (DVCs) will include both a USB 3.0 Device and a USB 3.0 Host.

The USB 3.0 Device will replace the current USB 2.0 Device in your DSCs/DVCs for connecting to your PC, or TV, or Blu-Ray Player.   You’ll use this USB port just as you always have to view, transfer, and print your photos from your camera.

The USB 3.0 Host will be inside the camera.  It will receive the USB 3.0 receptacle on the BluLightning Card that you purchase.  The USB 3.0 Host in the camera only needs to support USB 3.0,, there is no need for any USB 2.0 circuitry or a USB 2.0 PHY.  This can save significant area and power in the camera.  USB 3.0 only means USB 3.0 power savings which means more aggressive power savings that USB 2.0.  So using BluLighting maximizes throughput, minimizes area, and minimizes power usage.

See previous blog for pictures.

Synopsys Virtual Synposium Aug 31-Sept 2

I invite you to our first every Virtual Synopsys trade show where we will have a special area focusing on USB 3.0, HDMI, DDR, PCIe, SATA, and more.   Synopsys IP people will be on duty for live chat sessions throughout the conference.  I’ll be on duty August 31 from 3pm to 5pm so come to the Virtual Booth and lets chat.  Register here for the Synopsys Virtual Synposium.

The IOmega eGo drives will include USB 3.0 without a changes in price which means they’ve somehow been integrate it into their product with no change in cost, or in a grab for market share.   They look cool too.

“The Future of High Performance Flash Cards” (& USB 3.0)

Posted by Eric Huang on 19th August 2010

Today at the Flash Memory Summit, Lexar’s Jonathan Hubert presented “The Future of High Performance Flash Cards.”   The proposed standard called “BluLightning” transfers data faster than SDXC. In fact, BluLightning uses USB 3.0.

The Problem

Anyone buying a digital camera these days knows that transferring 2 or 4 or 8 GB of pictures takes forever.  This is limited by the card speed itself.  You can see from the LegitReviews.com website that the faster card readers are limited to about 27 MB/s.  This speed is probably limited by the SD read speed more than anything else. USB 2.0 might be the bottleneck, if it’s a bad host implementation or a poor host PHY, or similarly on the Device.  These days,the cheapest give-away USB flash drives still have this problem.

The fastest SD standard, SD UHS-1 goes up to only 104 MB/s compared to USB 3.0’s 320+ MB/s.   But, to my knowledge, these devices aren’t yet available.  If SD UHC-1 was available, you’d need a USB 3.0 card reader to make it work fast.

The point is this, the bottleneck is the flash card standard, not USB 2.0. 

The Solution – BluLightning

BluLightning is a flash card form factor with the same volume and physicimageal dimensions of a CompactFlash cards.  BluLightning uses USB 3.0 to provide a really fast data transfer PIPE from something like a Digital Camera to a Flash Memory Card.     USB 3.0 at 320+ MB/s  runs faster than SD UHS-1 at 104MB/s.   This means that there is room to grow.  You can use USB 3.0 to get your photos and videos from your Card to your PC much, much faster.  This is even more important for HD DVCs that record Gigabytes of data per hour of HD video recorded.

 USB 3.0 Cable to

I should point out at this point that this eliminates the need for a Card Reader, you just use a standard USB 3.0 Cable. So that saves Consumers some money.  You can use the same USB 3.0 cable for your camera, DVC, or card reader.

 
 
 
So speed is good, but why is BluLightning cool?

BluLightning cleverly employs USB 3.0 standard protocols, electricals, connectors, and cables.

Um, again, why is this cool?

This means that you can re-use existing USB 3.0

  1. Software Drivers & Stacks – you can leverage open source drivers, 3rd party software like those from our USB Software Alliance
  2. IP/Cores/Controllers – The protocol engines can be used “as is” like the IP from Synopsys
  3. PHYs – The PHYs are identical to existing USB 3.0 IP

It turns out that Synopsys has all this USB IP, specifically USB 3.0 PHY IP, USB 3.0 Digital Cores, and USB 3.0 VIP.

And our USB Software Alliance partners with USB 3.0 can provide compatible drivers and stacks.

Wow, that will save me months, and months of engineering time and money, while lowering my risk at implementing a new standard!

Probably. I couldn’t have said it better myself.

That’s not very objective!

BluLighting solves a problem everyone with a Digital Video Camera knows about and can feel.   (and Camera owners too).  The more leverage we get as an industry from existing standards, the faster we can get time to result, time to market, and value into consumers hands.

Who backs this standard today?

“BluLightning is a Lexar initiative with open industry meetings under the Compact Flash Association”*

This means the people that actually build digital cameras and DVCs

think and breathe this everyday and night.

How do I find out more?

Ask questions below, I’ll answer. I can get answers from Jonathan and his team behind BluLightning.  I’ll post more on this in the next few days including more on form-factor, applications, and other interesting stuff.
