SDK • Re: SOLVED : Anyone got assembly code for 32x32 => 64 that works?

Can't get more generic than the 32 bits meaning any of 8 different fixed-point types

I'd say the most generic type in audio on ARM is 32 bit integer * 32 bit integer -> 64 bits followed by 32 bit right shift (actually just take the top 32 bits of course potentially losing 1 LSB of rounding). In that case the lo*lo case can be discarded.

But the most generic overall by far in audio is of course 32 bit data * 16 bit multiplier into a 54 bit accumulator
