$14$ Consider the following code

$1w$$$6,0($$$4)$

lw $$4,5($$$7)$

beq $$6,$$$5,$ label $//$assume branch is not taken

sub $$7,$$$6,$$$2$

sw $$7,8($$$6)$

label: sub $$6,$$$7,$$$6$

a$.$ How many clock cycles does it take to execute the code if it is multi cycle

execution?

b$.$ How many clock cycles does it take to execute the code if it is pipelined execution?

c$.$ In which clock cycle does actual subtraction of $$3,$$$2$ takes place in case of multi

cycle execution?

d$.$ In which clock cycle branch target address is calculated in case of multi$-$cycle

execution?

e$.$ What happens during $8$th clock cycle in case of multi$-$cycle execution?
