A week ago, I posted about the Synopsys SSIC USB demo. Eric Huang has posted a new video with a lot more technical detail.  (If you can't see the preview, either enable all content, or click on this link: http://youtu.be/QzlgUNKTSXo:

If you watch carefully, there's a lot of information about the implementation, including a detailed list of what's at each layer.

Finding out about SSIC USB

Interested in information on SSIC USB? As I mentioned in "Synopsys demos SSIC USB using MCCI's USB 3.0 Host Stack", there's not yet a lot of information available outside the closed committee that's developing the specification. However, you can find a public presentation by Brad Saunders on the USB-IF website. He wrote:

An introduction to SSIC was included in a recent Intel Developer Forum (IDF) technical presentation titled: HSTS004: USB SuperSpeed: Extending to New Applications and Capabilities. Please visit http://www.intel.com/go/idfsessions for access to a copy of this presentation in the Technical Sessions Catalog (Hint: search for items containing USB in the title).

Another way to find is just to search for HSTS004 in the session ID, as shown here (click on the image for an enlarged version):

After you press Search, you'll see the a table with a link to the presentation, as shown below. (Again, click on the image for an enlarged version.)

Click on the PDF button to get the presentation. The SSIC information is on slides 8 through 13.

Synopsys demos SSIC USB using MCCI's USB 3.0 Host Stack

Synopsys did the world's first demo of SSIC USB (super-speed interchip USB) at the Intel Developers Forum in Beijing using MCCI's USB 3.0 host stack.  (Since this site uses HTTPS, you may need to press [Show All Content] to see the preview. If you prefer, use this link: http://youtu.be/jMeWZcpCbfI.)

Like HSIC USB, SSIC USB is designed to be used for chip-to-chip communication on a system board, rather than for connecting an external device. In its production form, SSIC USB will use the MIPI M-PHY for signaling between the chips. This will allow for much lower power than if the standard USB 3.0 PHY were used. 

Because our embedded host stack is the core of our Windows stack, MCCI's embedded USB 3.0 host stack is already ready for SSIC USB. (Although SSIC USB is supposed to be transparent to software, the technology behind SSIC USB also allows for variations in transfer speed; and the power management strategies may be different.) 

In my next post (Finding out about SSIC USB), I'll tell you how to get more info on SSIC USB. (The specification hasn't been published yet, but there's a little bit of information from USB-IF.)
