WebWithout forwarding, we’d have to stall for two cycles to wait for the LW instruction’s writeback stage. In general, you can always stall to avoid hazards—but dependencies are … WebThe SUB does not write to register $2 until clock cycle 5 causeing 2 data hazards in our pipelined datapath The AND reads register $2 in cycle 3. Since SUB hasn’t modiﬁed the register yet, this is the old value of $2 Similarly, the OR instruction uses register $2 in cycle 4, again before it’s actually updated by SUB
