- ; About:
- ; 1x1 8bpl cpu5 C2P for contigous bitplanes and no horizontal modulo
- ;
- ; This routine is intended for use on all 68040 and 68060 based systems.
- ; It is not designed to perform well on 68020-030.
- ;
- ; This routine is released into the public domain. It may be freely used
- ; for non-commercial as well as commercial purposes. A short notice via
- ; email is always appreciated, though.
- ;
- ; Timings:
- ; ~130% on (a1200 Blizzard) 040-25
- ; Estimated to run at copyspeed on 040-40 and 060
- ;
- ; Features:
- ; Performs CPU-only C2P conversion using rather state-of-the-art (as of
- ; the creation date, anyway) techniques
- ; Handles bitplanes creens of virtually any size (4GB)
- ;
- ; Restrictions:
- ; Chunky-buffer must be an even multiple of 32 pixels wide
- ; If incorrect/invalid parameters are specified, the routine will
- ; most probably crash.
- ;
- ; c2p1x1_8_c5_040_init sets only the chunkybuffer size/pos
- ; c2p1x1_8_c5_040 performs the actual c2p conversion
