Consider the code sequence below: 1. 2. add $15, $12, $11 lw $13, 4($15) lw $12, 0($2) or $13, $15, $13 sw $13,0($15) If there is no forwarding available, show how you ensure correct execution. Your answer should have a supporting diagram. You still do not have forwarding available. Show how you ensure correct execution with minimum delay. Your answer should have a supporting diagram. Remember you can use other methods for reducing the waiting cycles.
