6) Loop unrolling and register renaming can lead to an increase in code and the need for more resources. a) True b) False 4. Multiple choice questions (Check all that applies) 1) Two actions must be completed before a CBZ's branch can be taken, actions that take time. Obviously, one is to determine whether CBZ's register value is equal to 0. The other is to compute a) The CBZ's target address b) The CBZ instruction's register address c) The CBZ instruction's address 2) If forwarding cannot resolve a data hazard, the pipeline can be a) Stalled b) Bypassed 3) The following causes a data hazard for the 5-stage LEGV8 pipeline 11: ADD XO, X10, X11 12: SUB X12, XO, X13 "Forwarding" can resolve the hazard by providing the ALU's output (for it's stage 3) directly to the ALU's input (for i2's stage 3). a) Yes E No
