Consider the following instruction sequence for a 5-stage pipelined MIPS implementation 11: 12: 13: 14: 15: addi $s1, $50, 40 lw $s2, 0 ($s1) add $s3, $s2, $s1 add $54, $s3, $50 add $54, $s2, $s4 Assuming that the initial values of $50, $s1, $s2, $s3, and $s4 are 100, 200, 300, 15, and 30 respectively, and that memory locations 140 and 200 co values 60 and 90 respectively. Now consider the hazards and assume there is only ALU-ALU forwarding. What will be the final value of $s3?
