Question

Consider the code sequence below

lw   $t1, 4($t0) 

add $s2, $t1, $t2

lw   $t3, 16($t0)

add $s3, $t3, $t2

lw   $t4, 28($t0)

add $s4, $t4, $t2

Suppose there is no forwarding allowed, and for the result of a lw 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.
