Problem 3: Consider the following sequence ofinstructions and assume 5-stage pipelined datapath. add $sl, $s2, $s3 add $s2, $s1, $s4 sub $s1, $s1, $s2 lw $s1, 32 ($s0) a) Indicate data dependencies (RAW, WAW, WAR) in the above set of instructions b) Indicate hazards and add bubbles (nop instructions) to eliminate them c) Use full forwarding and indicate hazards that still remain after EXE-EXE forwarding. Eliminate the remaining hazards using nop instructions. Can the remaining hazards be removed using MEM to EX forwarding or else? d)
