Hi all,
A little question :
I want to copy a 559*155 image as fast as possible on Falcon.
First, I did a move.l (a0)+,(a1)+ copy with 2 loops (1 for x and 1 for y)
Then, I optimized a lot by using
movea.l screen_adr,a5
add.l #1152*155-512,a5
movea.l pictures_buffer,a6
add.w player_position,a6
add.w player_position,a6
rept 150
movem.l (a6)+,d0-d7/a0-a4
movem.l d0-d7/a0-a4,-(a5)
movem.l (a6)+,d0-d7/a0-a4
movem.l d0-d7/a0-a4,-(a5)
movem.l (a6)+,d0-d7/a0-a4
movem.l d0-d7/a0-a4,-(a5)
movem.l (a6)+,d0-d7/a0-a4
movem.l d0-d7/a0-a4,-(a5)
movem.l (a6)+,d0-d7/a0-a4
movem.l d0-d7/a0-a4,-(a5)
movem.l (a6)+,d0-d7/a0-a4
movem.l d0-d7/a0-a4,-(a5)
movem.l (a6)+,d0-d7/a0-a4
movem.l d0-d7/a0-a4,-(a5)
movem.l (a6)+,d0-d7/a0-a4
movem.l d0-d7/a0-a4,-(a5)
movem.l (a6)+,d0-d7/a0-a4
movem.l d0-d7/a0-a4,-(a5)
movem.l (a6)+,d0-d7/a0-a4
movem.l d0-d7/a0-a4,-(a5)
movem.l (a6)+,d0-d7/a0-a4
movem.l d0-d7/a0-a4,-(a5)
movem.l (a6)+,d0-d7/a0-a4
movem.l d0-d7/a0-a4,-(a5)
movem.l (a6)+,d0-d3
movem.l d0-d3,-(a5)
sub.l #512,a5
add.l #(559-320)*2,a6
endr
I have 2 questions :
- Is there a way to use also a7 without breaking everything ?
- Is there a faster way to do the job (on falcon) ?
Best regards
Thadoss

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
