- Short: ULTRA FAST 32bit C2P patch for OS chunky functions
- Author: rickprat@usit.net (Rick Pratt)
- Uploader: rickprat@usit.net (Rick Pratt)
- Version: 1.6
- Type: util/boot
-
- Very fast Replacement for the OS chunky pixel functions
- WritePixelLine8(), WritePixelArray8() and WriteChunkyPixels().
- Uses 32bit Chunky 2 Planar routines to write longwords to chipram.
- This makes it fast on 020+ cpus and REALLY fast on machines with 32bit
- chipram (A1200, A3000, A4000). Uses DoHookClipRects() to convert
- directly into the destination bitmap and so can only be used on
- OS 3.0 or greater.
-
- This version has c2p code just for doing non-aligned first/last
- longword masking. This gains about a ~6% speed up on my 030 40MHz
- and about a ~10% speed up on a 060. This is only for non-aligned
- tests and your speed up may vary.
