a$)$ Assume that the sequence of instructions is executed for TWO iterations of the loop. List

the instruction sequence executed. You can just list the line numbers.

b$)$ Identify all hazards that may affect the pipeline, causing it to stall. Note that such hazards

may include data hazards and control hazards. Identify each hazard to be a data hazard or

a control hazard.

c$)$ Without forwarding, add NOP instructions to ensure correct operation of the pipeline.

d$)$ With ALU$-$ALU forwarding, add NOP instructions again to ensure the pipeline is

working properly.
