PowerPC (powerUP) support via licensed SuperView-Library
========================================================
[ Please see ReadMe_REGISTER for where to find pricing information ]
Concept
-------
The most time-consuming routines of certain modules of SuperView-Library
have been ported to native PowerPC code and perhaps will profit a lot
from the presence of an installed powerUP system.
These "native modules" are located in a new subdirectory of LIBS:
called "svppc/", with subdirectories for each of SuperView-Library's
module types.
If any "native modules" are present, these will be used whenever applicable.
Should none of these modules be available, then this does not matter, since
the plain 68k code (which may be optimized for a certain 68k CPU, though)
will be used instead (fallback option).
Note, that SuperView-Library's native modules won't replace any of the
existing libraries or modules as such - they only do supply specialized
routines in native code for certain tasks.
When running any PowerPC code, you should have made sure, that there's
enough RAM on the powerUP board available - at least in an A4000 the
RAM interface from the CPU card (e.g. A3640) to the mainboard is so
slow, that even a 68040 could not access Fast RAM with full speed,
so possibly a PowerPC would suffer from the same problem.
You should take care, that there's still enough "fast" Fast RAM available,
even if all the libraries and code have been loaded: usually the graphics
are loaded at last - a 1024x768 graphics in 24 Bit will just take 2.4 MB
and in a dithered version again around 790 K.
If there's enough "fast" Fast RAM available, you can expect high speed
increases with most basic operations, especially when internal representation
conversions do take place.
(See the documentation of the single modules for further information.
PowerUP support usually is marked separately, on top of the
module documentation.)
Availability
------------
NONE OF THE PPC MODULES ARE FREEWARE - THEY WON'T APPEAR ON AMINET.
40 modules (+/-) are made available in a special powerUP PPC plugin
module package, which e.g. can be bought by registered SuperView/SViewNG
users or will be included with some commercial programs.
Also, there will follow some PPC modules, which will only be available
for exclusive shipment with some commercial programs (as also are the
concerned SV modules).
This is high end software, and its development must be financed
- so you have to pay for it to help ensuring further development.
