[30 marks] Consider the following code is executed on pipelined
datapath with only structural hazard solved.
lw $s0, 4($t0)
addi $t0, $s0, 100
add $s1, $s0, $t0
addi $s1, $t0, 1
and $t5, $s1, $s1
(a) Referring to the above code, which registers and how many times
each of those registers are affected by Data Hazard.
(b) Draw a diagram, by using arrow(s) to indicate Forwarding and
cross (X) to indicate Stall [Referring to an example below], to
illustrate how Forwarding and Stall are used to execute the above
code without having Data Hazard. The arrow should correctly
indicate the Forwarding to the upper or lower input of the ALU.
(c) Based on your answer at part (b), how many cycles are
required to execute the above code?
