Show how the following four consecutive instructions move through each stage of the five stage pipeline, similar to the example on slide 11 of lecture 17. This pipeline does not support any bypassing. Make sure the decode stage does not advance an instruction through the pipeline unless all data dependences are correctly resolved. (25 points) I1: add $s1, $s2, $s3 I2: lw $s4, 4($s4) I3: add $s5, $s4, $s1 I4: sw $s5, 8($s2)
