$1)$ For the following code draw multicycle pipeline diagram, identify hazards, show if there is pipeline stall or forwarding.

$t$0=10,$ $t$3=1016,$ $t$5=-2$

Address Value

$101215$

$101647$

$1020-5$

$10243$

Lw $t$5,4($$t$3)$

Addi $t$3,$ $t$5,13$

Sub $t$0,$ $zero, $t$3$

Sw $t$0,16($$t$3)$

Or $t$3,$ $t$0,$ $t$5$

And $t$5,$ $t$3,$ $t$3$
