sage Posted January 17, 2019 Share Posted January 17, 2019 Has anyone some experiences using multiplication in interrups? How to prevent unsave accesses? I am a bit afraid of chained sprites which are interrupted... Quote Link to comment Share on other sites More sharing options...
42bs Posted January 18, 2019 Share Posted January 18, 2019 Atari says, it is no good idea, as it cannot be restarted. Also I'd say they take far to long to be used in interrupts. But actually, I never tried it. Quote Link to comment Share on other sites More sharing options...
sage Posted January 18, 2019 Author Share Posted January 18, 2019 They are faster than doing it by hand, at least for 16x16 Quote Link to comment Share on other sites More sharing options...
42bs Posted January 18, 2019 Share Posted January 18, 2019 As to my understanding, the math engine is not linked to the sprite engine. The only problem is that the multiplication cannot be "restarted". Means, no math in foreground if you want to use it in the interrupt.

I interpret it that you are not allowed to do mult and sprite in parallel. But if I can do multiplications while I interrupted the sprite engine, it is fine with me.
