Ok, I give you an example :
I lauch hatari with graoumpf tracker.
I then press "AltGR + Pause" keys to activate the debugger.
Then, I use the dd command (DSP disasemble code in P memory from current PC"
I get :
DSP disasm 299-2a1:
0299: 228f0d (02 cyc) cmp a,b r4,b
029a: 0eb299 (06 cyc) jmi p:0x0299
029b: 64f400 000c60 (04 cyc) move #0x000c60,r4
029d: 44f400 000300 (04 cyc) move #0x000300,x0
029f: 440800 (02 cyc) move x0,x:0x0008
02a0: 0c02a3 (06 cyc) jmp p:0x02a3
>
DSP disasm 2a1-2a9:
02a1: 0a0f20 (04 cyc) bset #0,x:0x000f
02a2: 0c029b (06 cyc) jmp p:0x029b
02a3: 0a0fa0 0002b4 (08 cyc) jset #0,x:0x000f,p:0x02b4
02a5: 578900 (02 cyc) move x:0x0009,b
02a6: 20003a (02 cyc) asl b
02a7: 20003a (02 cyc) asl b
02a8: 568e00 (02 cyc) move x:0x000e,a
DSP cycles are displayed for every instruction.
I would like to verify them (if I didn't do a mistake in my code).
The best would be to compile some DSP code which would display the cycles.
Else, if I could get some examples, I would write them back to hatari and test them in disasm mode.
Is it clearer like this ?
Thanks for the help,
Regards,
Laurent

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.
