i'm tempted to suggest making it possible to select the different
implementations, you know, by the soc.config structures you can see
building up, there.

then the code is still around and useable when we do the larger cores and
sqrt and rsqrt make it worthwhile to use pipelines.

but the abstraction layers building up because of that approach is getting
really high.
