Given that:
subtract immediate instruction with dst: 1 src: 1 and immediate: 1 at 12
the PC at time 6 = 12
value of cell 127 at time 6 = 2
Prove that:
value of cell 127 at time 7 = 2
The following properties may be helpful:
- not (127 = 1)
- 6 + 1 = 7
if the following are true:
- subtract immediate instruction with dst: dst src: src and immediate: imm at i
- 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
if 6 + 1 = 7, then value of cell 127 at time (6 + 1) = value of cell 127 at time 7
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.
