[hatari-devel] Little question with relative_interrupts

[Laurent Sallafranque]

Hello,

While reading code in int.c and int.h (for the crossbar), I asked me the 
following question :

Extract from int.c

  Thanks to Arnaud Carre (Leonard / Oxygene) for sharing this method 
used in Saint (and also
  used in sc68).

  Conversions are based on these values :
    real MFP frequency is 2457600 Hz
    real CPU frequency is 8021247 Hz (PAL european STF), which we round 
to 8021248.

  Then :
    8021248 = ( 2^8 * 31333 )
    2457600 = ( 2^15 * 3 * 5^2 )

  So, the ratio 8021248 / 2457600 can be expressed as 31333 / 9600


Are these values still OK for a falcon (where the CPU is ~16 000 000 and 
not 8 021 248 ?

If no, would this explain that some demos/games need to run at 32 Mhz ?

Regards

Laurent
