[Discuss-gnuradio] UHD Announcement - December 13th 2010 - MIMO cable support

[Josh Blum]

Hello list,

I would like to announce support for the MIMO cable with UHD. The
support is experimental, so its not in the mainline yet, and is only
available for USRP2 at the moment.

The source for the FPGA code has not yet been pushed but you can get the
pre-built images here:

The supporting host code is available on the packet_router branch of the
uhd repo:

Here is an excerpt from the docs on the MIMO cable in UHD:

> ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
> MIMO cable configuration
> ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
> Using the MIMO cable, two USRP devices can be grouped together in a 
> multi-device configuration.
> Only one device in the configuration can be attached to the ethernet.
> This device will be referred to as the master, and the other device, the 
> slave.
> 
> * The master provides reference clock and time synchronization to the slave.
> * All data passing between the host and the slave is routed over the MIMO 
> cable.
> * Both master and slave must have different IPv4 addresses but in the same 
> subnet.
> * The master and slave may be used individually or in a multi-device 
> configuration.

I hope that explains it. Feedback is welcome!

Thanks,
-Josh
