Well it looks like this is not going to be possible on the Cyclone IV
chip on the Nano I have. I looked at a commercial core that runs
on a Stratix II and from the number of LEs they use I think I have
figured out how they have implemented it. They have done it in the
way I would like to have done if I had, had enough LEs available.
I should not have got diverted onto that anyway as the priority
is DATV-Express. I have now received the feedback from the
BATC about my talk and it seems to have received good marks.
Thanks to everyone that put my talk near the top of their list.
