Synopsys demos USB 3.1 support with MCCI's USB host stack

I'm attending the USB 3.1 Developer Days conference in Seattle, and I was pleasantly surprised to see Synopsys demonstrating USB 3.1 host, talking to a USB 3.1 BOT device, using MCCI's host stack on Windows 8.1. (Click on the picture to see the details.) Yep, 918 megabytes per second, or roughly 7.5 gigabits/sec on the bus.

Note that we're getting 918 MB/sec read speed, roughly twice as fast as MCCI's stack with USB 3.0 host controllers.The really gratifying thing is that no modifications to MCCI's USB host stack were required. If you zoom in on the device manager portion of the screenshot, you'll see that they're using MCCI's host stack, along with MCCI's high-performance mass storage drivers. (Which I've written about before: see "MCCI's UASP and BOT Drivers".) Of course, the Microsoft stack would also have worked; we're pleased they chose to demo using our stack.

Since MCCI's Windows stack consists of our embedded system stack (TrueTask® USB), plus Windows-specific wrappers, this means that our embedded stack can offer similar performance for USB 3.1 systems, in addition to providing the peace of mind of a stack that has been tested at USB-IF PIL, and used by millions of users on Windows systems.

Of course, the kudos should really go to Synopsys -- it's very impressive. Glad we could be a part of it. I'm looking forward to even better performance once we have a chance to tune the software part of the demo.

How to find the HSIC USB specification

in HSIC USB

Sometimes specs are hard to find. MCCI's pretty active in developing products for that support High Speed Inter-Chip USB (HSIC USB) (such as the MCCI Catena 1910), and I'm often asked where to find the HSIC specification. The specification can be freely downloaded, but it's not published as a stand-alone document. Instead, it is part of the USB 2.0 Specification zip file.

The link to the USB 2.0 specification zip file (as of November 22, 2011) is:

USB Implementers Forum Releases MBIM 1.0 Specification

The USB-IF Device Working Group yesterday published the Mobile Broadband Interface Model (MBIM) V1.0 specification.

It's a big specification -- 225 pages. It has to be: it defines a standard control/data plane for 3G and 4G wireless data modules. Because it allows for interchangeable modules with a common interface (regular USB or HSIC USB, used in MCCI's Catena 1910), the spec will have wide use in M2M applications. In addition, you can expect to see in-box support in Windows 8.
