The following table gives a sequence of instructions that are performed on a 4?stage pipelined computer. Detect all hazards. For example if instruction m uses operand r2 generated by instruction m?1, then write m?1,r2 in the RAW column in line m.
Note that some of the hazards are technical hazards and not real hazards. For example, instruction 3 does not
suffer a RAW hazard on r1 because any delay will have been swallowed by the previous instruction.
