If you are looking for more speed, take a look at avr-gcc.  The floating
point library in that package is very good.  It takes about 600 or so
instructions (depending upon what you use) and basic operations are done in
~500 cycles.  For my needs, mult/div/cos/sin/add/sub I got around 1.6k
ops/sec/mhz or about 25 kops/sec at 16mhz.

Stefan,

just checked, the site says 20Mhz, so does the datasheet...
Interesting though, it *might* be good enough, to do what I need, need to
check that my version of CV-AVR supports it and check supplies, it would be
DAMNED nice if it did run at 24Mhz..
