Question $1$ Accumulator Architecture

In the following, we consider a hypothetical machine with an $8-$bit accumulator $($AC$)$ as register

for computations, an $8-$bit nrrurram muntor $($PC$)$ and an &$.$hit instruction register $($IR$)$:

Each machine instruction consists of one byte. The operation code is contained in the three

most significant bits of a machine instruction. The other five bits contain the specification of an

operand. This is always a memory address.

The following bytes are now stored in memory:

i$)$ Write the content of the memory mnemonically$/$symbolically in the left table.

ii$)$ Simulate the execution of the machine program in the right table. Document in each row

the state of one machine instruction cycle as follows: The "cycle" column denotes the

current instruction cycle, the $"PC"$ column shows the $PC$ register value at the beginning

of the instruction cycle, while the $"$IR$"$ and $"$AC$"$ columns show the IR and AC registers

at the end of the instruction cycle. Write the address and content of a modified memory

byte in the "memory" column, if required.

Note: You can use the symbolic representation for the $"$IR$"$ column and the decimal

representation for values in the $"$AC$"$ and "memory" columns.
