Consider the following instruction sequence executing on a $5-$stage ARM pipeline with

static branch prediction and branches are resolved early in the execute stage. The

instruction sequence shown results in control hazards. $($Note that the loop counter in R$0$

is set to $2.)$ Suppose the CPU uses a static branch prediction policy of predict$-$always$-$

untaken. How many cycles are wasted due to control hazards? Assume the program

executes several more non$-$branch instructions after the label DONE.

a$.0$

b$.2$

c$.4$

d$.8$

e$.12$
