Only need to answer the Q1:

Q1:

Repeat the following question, but now assume that the pipeline does use forwarding. Provide a drawing.

Q2:

Make a drawing(example mentioned below) that shows the clock cycle at which each of the instructions in the sequence given below would be completed, assuming the 5-stage MIPS pipeline without forwarding discussed in class, and numbering the clock cycle at which the first of the instructions is fetched as clock cycle 1. You must examine and show the dependency for each instruction in the given sequence. Do not reorder the instructions. Instructions are fetched and executed exactly in the order given below, with the pipeline stalling if necessary.

addi $s2, $s2, 1

add $s6, $s1, $s3

add $s1, $s2, $s3

lw $s5, 0($s1)

lw $t1, 0($s5)
