Maybe.

Probably less so if real.c is rewritten so that it can use 32/64
arithmetic instead of 16/32.  This gets more work done per cycle.
IIRC, Roman Lechtchinsky is looking into that because alpha-unicosmk
doesn't have a 16 bit type.

Another alternative is to use a completely different, more efficient
soft fp implementation.
