Given that:
instruction #7 is
addi dst=4 src=4 imm=1
the PC at time 7 = 7
value of cell 5 at time 7 = 4
Prove that:
value of cell 5 at time 8 = 4
The following properties may be helpful:
- not (5 = 4)
- 7 + 1 = 8
if the following are true:
- instruction #i is
addi dst=dst src=src imm=imm
- the PC at time t = i
- not (other = dst)
then value of cell other at time (t + 1) = value of cell other at time t
- instruction #i is
if 7 + 1 = 8, then value of cell 5 at time (7 + 1) = value of cell 5 at time 8
if the following are true:
- a = b
- a = c
then b = c
if the following are true:
- a = b
- b = c
then a = c
Please write your proof in the table below. Each row should contain one claim. The last claim is the statement that you are trying to prove.
