To USB or Not to USB


Fastest USB 3.0 IP in the Universe

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.


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.

*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.)
