Is LUT sharing between adjacent cogs very important?
I ask because we are out of room in the -A9 now.
While LUT sharing has some neat aspects, part of me likes the idea that the cogs are all, ideally, very independent, and things which might dictate use of an adjacent cog, as opposed to any cog, kind of undermines that. We ARE stuck, somewhat, already, because of the fast DAC channels to I/O pins.
I'm a little loathe to start stripping other things down to support this feature.
Putting in 32-bit latches is less painful, but not much, really. It doesn't take much more to support full LUT sharing.
