4.20 Problem in this exercise refer to the following instructions sequence: a. ADD R1, R2, R3 LW R2, 0(R1) LW R1, 4(R1) OR R3, R1, R2. b. LW R1, 0(R1) AND R1, R1, R2 LW R2. 0(R1) LW R1, 0(R3). 4.20.1[5]<4.7> Find all data dependences in this instruction sequences. 4.20.2[10]<4.7> Find all hazards in this sequence for a 5-stage pipeline with and then without fowarding.
