if the following are true:

• the PC at time 0 = 0
• instruction #0 is addi dst=3 src=0 imm=3
• instruction #1 is addi dst=4 src=0 imm=0
• instruction #2 is addi dst=5 src=0 imm=0
• instruction #3 is addi dst=5 src=5 imm=7
• instruction #4 is addi dst=4 src=4 imm=1
• instruction #5 is beq left=3 right=4 imm=1
• instruction #6 is jump imm=3

then value of cell 5 at time 14 = 21
