WebYour first loop uses the adder twice in each iteration; your second loop uses an adder once, and a multiplier once. The first loop does two additions sequentially; your second loop does them in parallel, so what you probably see is that a multiplication is faster than two additions. – Sergey Kalinichenko Feb 17, 2014 at 2:40 1
