[GSoC] Co-Processors Update #1

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

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!
