Hi,

Does anybody know if there is a support for hardware multiplier on Arduino IDE ? If yes, then which devices does it support ?

(Apologies if I am at the wrong forum topic).

Thanks,
Ahmed.

A hardware multiplier other than the one in the processor is going to take a lot of your limited I/O.
Are you maybe looking for a DSP architecture?

Yes.

It definitely uses it for an Arduino Uno...and hopefully for any other chip with a multiplier.


(I assume you meant for the AVR chip on the Arduino....you didn't say)

You did not say whether you wanted integer, floating point or analog 8^), but here is a floating point co-processor:

hi, For example lets take an Arduino Mega with ATmega2560, I am not able to find info about its capabilities of floating point multiplications (if there are any) , can you kindly shed some light on this?
Thanks.
