Hello everyone,

Apologies for the delay in brining the update. There was a confusion  
with  
the hardware from TI and I was traveling the week GSoC started. Here are  
some brief points, for more detailed info please consult the wiki page:  
[http://gnuradio.org/redmine/projects/gnuradio/wiki/Keystone2](http://gnuradio.org/redmine/projects/gnuradio/wiki/Keystone2)

Logistical Updates:

- The hardware is expected to arrive later this week
- TI wants me to present results at a conference in the first week of  
August so earlier timeline than expected!

Progress Updates:

- Philip and I are exploring the use of get\_user\_pages to perform direct  
IO  
with co-processors without having to perform an extra copy to the  
kernel.  
Example on github
- Tom is helping me with gnuradio-runtime so that we can setup direct IO  
from gnuradio blocks to act directly on the gnuradio buffers.
- We decided to use the Fast Fourier Transform Co-processor (FFTC) as  
our  
test

That’s about it for now. If you are interested please read through the  
wiki  
page and offer any questions/suggestions.

Thanks!
