Pow erM ath
Note:
PowerMath
is not
available
on the
Turbo 040i
or if other
enhanced
SANE soft­
ware such as
RadiusMath
is installed.
The capability to turn off the cache is provid­
ed. With the cache off, the Mac still runs at the
accelerated clock speed, but perform ance is sig­
nificantly reduced.
P I PowerMath (Turbo 040 only, not available on
Turbo 040i)
- Allows you to turn DayStar’ s
PowerMath on and off. QuadControl provides two
versions of PowerMath. The first, normal
PowerMath, replaces A pple’
s SANE (Standard
Apple Numeric Environment) routines, which do
all floating point operations in software, with ver­
sions which use the math coprocessor. The second,
Enhanced PowerMath, provides greater perfor­
mance by decreasing the amount of overhead nec­
essary to get to a coprocessor-based SANE routine.
Enhanced PowerMath is functionally similar to
A pple’
s Omega SANE, which was released with
System 7.0.1. Both versions of PowerMath maintain
A pple’
s high level of numerical accuracy.
