Consider the code sequence below Iw $t1, 4($to) add $2, $t1, $t2 Iw $t3, 16($t0) add $s3, $t3, $t2 Iw $t4, 28($t0) add $4, $t4, $t2 Suppose there is no forwarding allowed, and for the result of a Iw to be consumed by the following R-type of instruction requires 2 bubbles to be placed between the two instructions. Is it possible for the scheduler to juxtapose the commands in such a way that there is no need for any bubbles? If yes, give an example of how it can be done.
