Fill in the pipeline for he following instructions (Note: instructions A, B, C, D, E, G are not branch instructions): A, B, beq G, C, D, E, G C. Assume beq G is taken. Does this program execute correctly? Why? Hint: beq G means jump to the instruction G D. What do you need to do (and when, i.e., which cycle) to get the correct behavior? Hint: What should happen to instructionsC, D, E 12 Cycle LI~ [ LI~ LI~ i L= L m x
