Given the following MIPS code: or $15, $13, $14 sub $16, $13, $14 1w $12, 0 ($14) add $11, $15, $12 The data dependency involves which register? $11 $12 $13 $14 $15 $16 Question 19 (3 points) The most efficient way of solving the above data dependency is: stall only dynamic prediction only forward only adding additional hardware stall and forward
