FPE benchmarks
Ok folks, here are three of the Orca/C floating point benchmarks done under
four different conditions. Where the FPE was used, it was done using the
Orca FPE sysfloat library.
Note that I have the FPE in slot 3 without overriding slot 3's functions
(the control panel is set to the default).
Presumably, the FPU would have similar performance to the FPE.
I hope this helps.
