Draw the pipeline execution diagram for the two sequences of instructions given below.

IDEX IFID EX Data IFMD FND.RegisterRt unit Figure 1: Pipelined datapath with two forwarding paths Draw the pipeline exccution diagram for the two scquences of instructions given below when executed in the pipelined datapath shown in Figure 1. The datapath implements forwarding for EX and MEM hazards. Your pipeline execution diagram should clearly indicate the forwarding paths that may be used and clearly mark a bubble (i.e, stalled instruction). An example of a pipeline execution diagram is given in Figure 2. You are supposed to draw a similar diagram but for the following sequence of instructions: Sequence (A) add $t0, $t2, $t1 lu St3, 4(Sto) lu St2, 0($t2) or St.3, $t5, $t3 su St3, 0($t5) su St1, 12(Sto) lu Sto, 8(t1) or Stl, St2, $to add $t2, $t1, $t0 sub $t2, $t0, Sti Time (in clock lw $2, 20 31) bubble and becomes nop and S4, $2, $5 or $8, $2, $6 add 59, S4, $2 Figure 2: Sample pipeline execution diagram. Your diagram should look similar but you do not need to shade the individual blocks IDEX IFID EX Data IFMD FND.RegisterRt unit Figure 1: Pipelined datapath with two forwarding paths Draw the pipeline exccution diagram for the two scquences of instructions given below when executed in the pipelined datapath shown in Figure 1.
