About PowerFPU
ZRPowerFPU
 is a high-performance 68K FPU emulator for the Power Macintosh from John
H`Neil & Associates.  By working closely with the built-in Apple 68K emulator and re-directing 68K
QFPU calls to the high-speed PowerPC CPU, PowerFPU provides extremely fast 68K FPU
]emulation.  PowerFPU is over ten times faster than SoftwareFPU, John Neil & Associates
 other
`low-cost FPU emulator, and faster than some versions of the Motorola FPU chip itself!  The chart
Wbelow shows where PowerFPU performance falls in the range of Macintosh FPU performance:
