1. Suppose we have a 5-stage pipeline CPU and run the following instructions: or $tl, $t2, $t3 or $t2, $tl, $t4 or $tl, $tl, $t2 1.1. What dependencies are there in the code? 1.2. Suppose there is no forwarding. What hazard may happen? Draw the pipeline diagram and insert stall (nop) to prevent these hazard. 1.3. If the pipeline has full forwarding. Are there still hazard? If so, draw the pipeline diagram and insert stall (nop) to prevent the hazard....
