Problem $4$ : The following sequences are implemented in a $5-$stage pipeline with no structural hazard.

Lw t$1,0($t$0)$

Lw t$2,4($t$0)$

Add t$3,$ t$1,$ t$2$

Sw t$3,12($t$0)$

Lw t$4,8($t$3)$

Add t$5,$ t$1,$ t$4$

I. Draw the pipleline flow of these codes assume no forwarding.

II$.$ Draw the pipleline flow of these codes assume forwarding available.
