a) What is MIPS pipeline CPI? (2) b) What is a control hazard? How can we avoid stalling the pipeline some of the times? What happens if this technique goes wrong? (3) c) Consider executing the following MIPS code on the single pipeline data path with hazard detection and forwarding units. add $5, $6, $7 1w $6, 100 ($7) sub $7, $6, $8 How many cycles will it take to execute this code. Where/When will stalls be inserted? Which values are forwarded? (2+2+1)
