How faster would the machine be if load time is $2$ cycles?

What if two ALU instructions could be executed at once? Second Example on CPI

Given: instruction mix of a program on a RISC processor

What is average CPI?

What is the percent of time used by each instruction class?

Average $\frac{C}{P}$I $=0\mathrm{.}5+1\mathrm{.}0+0\mathrm{.}3+0\mathrm{.}4=2\mathrm{.}2$
