On many CPUs it's fully pipelined, so throughput is 1 per clock, but you can only achieve that if you have three independent multiplies in flight. (FP multiply on Haswell is 5c latency, 0.5c throughput, so you need 10 in flight to saturate throughput). http://www.learningaboutelectronics.com/Articles/How-to-perform-addition-subtraction-multiplication-division-in-x86-assembly.php memorial hermann nurse hotline

"WebTo multiply by 10: y = (x << 3) + (x << 1); To divide by 10 is more difficult. I know of several division algorithms. If I recall correctly, there is a way to divide by 10 quickly using bit shifts and subtraction, but I can't remember the exact method. If that's not true, then this is a divide algorithm which manages <130 cycles. " - How to divide in x86
