This is just so awesome - back in the day it's this itch "how does the hw do it?" that makes you wonder, and then, some 25 years later, someone figures it out and now you know.
Perhaps I'm misreading but one tiny inaccuracy perhaps: the 68K has MULS and MULU of course as well as even DIVS and DIVU.. It's quite capable though clearly not fast enough for this purpose..
- jacobush 11y agoPeople did not use these instructions much in games etc, it was more common to use a lookup table.
- egypturnash 11y agoThe 68k has multiply instructions - but in the beginning he's talking about how the sound chip modifies the volume of sound sample data. He is however wrong about the 68k not having multiplication when he mentions avoiding it while writing his mod player.
