I was talking about GA's SRAM interface, p. 9 of 

     http://www.greenarraychips.com/home/documents/greg/AP003-110810-SRAM.pdf 

which says

    The software shown in this revision is provides its masters with
    practical memory read cycles on the order of 250 ns using the full
    featured version of the interface node software, or 200 ns using the
    degenerate version discussed below.

Yeah I've been looking at that stuff.  It sounds like Chuck is having
fun.  He is finding ways to solve with one "universal" device, various
1980's-ish design problems that would have taken bags full of
specialized chips in that era.  Unfortunately as devices have gotten
more powerful, the challenges facing them have gotten bigger as well.
So it still seems to take specialized hardware to solve the problems of
the present day.
