I just wanted to let folks know that I've posted some initial notes from the WG call on the
gnuradio.org wiki:
http://gnuradio.org/redmine/projects/gnuradio/wiki/Call20140812
There isn't a lot of information there, but I think the discussion surrounding Alfredo's GSoC work was worthwhile, particularly on driving towards understanding the minimal set of changes need to GNU Radio core to support various interesting co-processor functions.
I'll also note that I don't plan to have another call until after GrCon'14. So hopefully those of you interested in this topic will be able to attend and join the discussion when we break out into the working groups during the conference.
