There is no way to know how a specific Intel CPU does it. There is also no generic method to do it. Likely Wikipedia lists multiple different methods of computing multiplication in computers. Have you done any research before asking, and is this some kind of homework question? | |

| Mar 1, 2023 at 16:49 | comment | added | periblepsis | Weier, You mentioned an instr. set that has a long history and for which there isn't a single answer (it was done different ways at different times) and then you ask for how it is done, generally. Folks that do these things apply a lot of knowledge to varying goals. So I think the better answer for you is to start by learning about the Booth algorithm. I've not read this, An effective educational module for Booth's multiplication algorithm, but the title sounds good. | |
