if the following are true:

• the PC at time 0 = 0
• instruction #0 is addi dst=7 src=3 imm=0
• instruction #1 is addi dst=8 src=4 imm=0
• instruction #2 is addi dst=9 src=5 imm=0
• value of cell 3 at time 0 = 13
• value of cell 4 at time 0 = 11
• value of cell 5 at time 0 = 20

then value of cell 8 at time 3 = 11
