now you've got it.

and that internal format is trivial.  single-bit wires.

to do a 32-bit to 32-bit translator is a MASSIVE piece of silicon that
has to preserve every nuance of the instructions...

oh... err... and once it's translated to POWER, it has to go through
*another* translation process, to be decoded into the internal format?

errr no.
