Looking for CD32 beta tester(s) for a new cd.device
« on: December 14, 2025, 09:28:00 AM »
Hi all !

I'm looking a for CD32 owner(s) for checking my new cd.device :

You need to have a real CD32 (no emulation) for checking CDs, doing benchmarks, verify files integrity...

You can use of course LoadModule for loading my new versions, or burning in eproms, as you want...

I already have many new versions, need deep checking now !

So your just after some one to test it, to see thats its still all working ok?
There is no changes etc etc, just code optimisation to reduce size?

Yes, and only this is already a big work...


One quick example with the original (20 bytes) :
Quote
_BCDtoBIN
move.w d0,d1 ; isolate one's digit
andi.w #$000F,d1
lsr.w #4,d0 ; isolate ten's digit
andi.w #$000F,d0
mulu.w #10,d0 ; multiply ten's digit
add.w d1,d0 ; add one's digit
rts

This one is faster or not (14 bytes) on a 020 ?
Quote
_BCDtoBIN
moveq #16,d1
divul.l d1,d1:d0
mulu.w #10,d0 ; multiply ten's digit
add.w d1,d0 ; add one's digit
rts

Or maybe this one (18 bytes) :
Quote
_BCDtoBIN
unpk d0,d1,#0
lsr.w #8,d1
mulu.w #10,d1
andi.w #$000F,d0
add.w d1,d0
rts

Good question, isn't it ?!
