$[\frac{15}{15}\frac{?}{?}\frac{15}{15}\frac{?}{?}\frac{25}{10}\frac{?}{15}]$ A$.2>$ Use the following code fragment:

Loop: $1dx1,0(x2)$ ;$10adx1$ from address $0+x2$

addi $x1,x1,1,$;$x1=x1+1$

$sdx1,0,(x2)$ store $x1at$ address $0+x2$

addi $x2,2,4,$;$x2=x2+4$

sub $x4,x3,x2,$;$x4=x3-x2$

bnez $x4,$ Loop ;branch $to$ Loop $ifx40$

Assume that the initial value of x $3$ is $x2+396.$

d$.[15]$ C$.2>$ Show the timing of this instruction sequence for the $5-$stage RISC pipeline with full forwarding and bypassing hardware, as shown in Figure C$\mathrm{.}6.$ Use a pipeline timing chart like that shown in Figure C$\mathrm{.}8.$ Assume that the branch is handled by predicting it as taken. If all memory references take $1$ cycle, how many cycles does this loop take to execute?
