Web17 iul. 2014 · 2. If I have to use the VPMULHD and VPMULLD instructions for 64-bit integers multiplication, I need to use those instructions to multiply 2 32-bit integers first. They multiply 2 32-bit integers but only store the high part and low part of the 64-bit result reperately. So I need two instructions for 32-bit integers multiplication. Web7 mai 2024 · Higher end 16 and 32 bit processor cores on the other hand typically did have hardware multiply instructions and furthermore worked with larger data word sizes. Some of the high-end 8 bit (data word size) micro-controller architectures such as the "atmega32" and the "pic18" decided to add a multiply instruction. Since this was a new feature for ...
