Hi,

You're right. Nios II/f does support hardware multiplication check this link https://www.intel.com/content/www/us/en/docs/programmable/683836/current/multiply-and-divide-performance-83984.html. So not necessary to add floating point hardware anymore.

Thanks,

Best regards,

Hello,

thank you, for your reply,

also the link you suggests to make multiplication in assembly code. I am writing in c++, how will I write those functions ? (Mul r1, r2, r3)??

Is there any other means to make the “ 64 bit double precision “ multiplication more faster, in nios II. .?
