Re: [hatari-devel] Does CPU setting work?

Hi,

I think this is one of the first problems to fix for the 68030 accuracy emulation (I mean a real 16 Mhz clock) and not a 8 Mhz with cycles divided by 2.

I also noticed this but wasn't sure if the problem was specific to my own build...

The implementation also looks like it divides instruction cycles by N (e.g. divide by 2 for 32mhz?) and some instructions take an odd number of cycles (e.g. several common ops take 3 cycles)... so it's only approximately 2x speed.

Hi,

to my surprise, setting CPU to 16 or 32 MHz makes no difference in performance of my CPU/DSP app at all (when I measure FPS for example). I tried the "basic" Hatari only as Hatari/WinUAE is giving my a nice set of bus errors and crashes with my DSP stuff.

Is this intentional/known fact?
