;
; 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
;
