Given that:
instruction #5 is
addi dst=1 src=2 imm=0
the PC at time 5 = 5
value of cell 2 at time 5 = 1
Prove that:
value of cell 1 at time 6 = 1
The following properties may be helpful:
- 5 + 1 = 6
- a + 0 = a
if the following are true:
- instruction #i is
addi dst=dst src=src imm=imm
- the PC at time t = i
then value of cell dst at time (t + 1) = (value of cell src at time t) + imm
- instruction #i is
if 5 + 1 = 6, then value of cell 1 at time (5 + 1) = value of cell 1 at time 6
if the following are true:
- a = b
- a = c
then b = c
if the following are true:
- a = b + c
- b = d
then a = d + 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.
