I looked for specifications on it, and couldn't find any in-depth
information, but I did see a reference to a 64-bit floating point
unit...I interpreted that as a unit that handles 64-bit floats, though
it could be a vector unit handling 2 32-bit floats, or something similar.
If it does double-precision through software, that would slow it
down a lot...nothing to do with it being a RISC processor, though.
