[QUOTE=xfcemint;n1208141]The problem with adding a texure unit is that it is a
lot of work.

It is much, much easier to just use a special instruction for bilinear
filtering.

So, for start, perhaps it is a better idea to not use a texture unit.[/QUOTE]

this sounds exactly like the kind of useful strategy that would get us some
reasonable performance without a full-on approach, and, as a hybrid processor
it would fit better and it's also much more along the RISC strategy.  thank you
for the suggestion.
