3. The following sequence of instructions is executed on a 5-stage pipelined datapath: add r5,r2,r1 lw r3,4(r5) w r2,0(r2) or r3,r5,r3 sw r3,0(r5) i. Indicate dependences (data hazards). If there is no forwarding or hazard detection, insert NOPs to ensure correct execution. ii. Use a combination of instruction reordering and forwarding (only when needed if reordering is not enough) to fix the data hazards if possible; beyond this, if NOPs (stal are needed use them. 3.
