- DESCRIPTION
-
- This CPU blitting library is used by programs like Personal Paint when
- the "Settings/Graphics/Amiga Blitter" setting is switched off.
-
- This library automatically detects a CyberGraphX 40.100+ environment,
- and informs the client software (e.g. Personal Paint) that it is safe to
- allocate Fast RAM instead of Chip RAM even if the memory has to be
- accessed by the graphics.library. CyberGraphX "clones", which have a
- parallel system of version numbers, are detected and will not trigger
- this condition, as this would currently crash the system.
-
- This library uses the PowerPC CPU to emulate a 32-bit blitter, whereas
- all libraries prior to version 2.0, like the original Amiga, worked with a
- 16-bit blitter model. This release is about twice as fast as the 1.x
- libraries. In particular, a simulation of average blitter operations
- of this PowerPC version tested on a PowerUP board with a 603e CPU running
- at 150 MHz resulted in a software blitter more than twice as fast as the
- AGA Amiga hardware blitter, with the advantage of not requiring precious
- Chip RAM.
-
- Additional functionality has been integrated in this library to better
- support future programs.
-
- To use this library, please update the library name in the "Startup_1.set"
- program settings file. In no case should any of the library files be
- renamed.
-
- The automatic detection of a RTG environment supporting bitmaps in Fast
- RAM can be overridden by setting the "PBlit_ChipMem" environment variable,
- which can be used to force the allocation of bitmaps in Chip RAM or
- Fast RAM.
-
- This blitting library requires the "ppc.library" to be present in the
- system, plus a PowerPC kernel compatible with the version released by
- Phase 5.
-
- Version 2.3 fixes an incompatibility introduced by changes in the
- software included with newer Phase 5 PowerPC boards. The original
- library, which may be required for some older PowerPC configurations,
- is included in the "old" directory.
