For those folks who keep track of new hardware devices that could be  
amenable to building SDR systems, Cypress Semi has finally publicly  
announced their USB 3.0 FX3 SuperSpeed USB controller:

[http://www.edn.com/article/517788-USB\_3\_0\_controller\_embeds\_microcontroller\_for\_customized\_applications.php](http://www.edn.com/article/517788-USB_3_0_controller_embeds_microcontroller_for_customized_applications.php)

This controller provides the same sort of GPIF interface as used on the  
original USRP1 to provide a digital data path up to a USB 3.0 SuperSpeed  
host device (i.e., a PC). Real-world sustained data rates for USB 3.0  
SuperSpeed devices have been hitting close to 300 MB/sec (and that is  
before  
you get into the new bulk streaming mode). Could make for a very  
interesting multi-transmit/multi-receive system (assuming you’ve got a  
PC  
that can actually do something with that much data coming in, which is  
still  
a big challenge).

Thunderbolt is another possibility. “Up to” 10 gigabits per second per  
each of two channels.
