After first ADD instruction, A = 25 + 0 so, A = 25
CY = 0
AC = 0
P = 1
After second ADD instruction 34 +25
D7 D6 D5 D4 D3 D3 D1 D0
0 0 1 1 0 1 0 0
0 0 1 0 0 1 0 1
0 1 0 1 1 0 0 1 = A
CY = 0 as no carry from D7 bit
AC = 0 as no carry from D3 to D4
P = 0 as no. of 1 in accumulator is even
After 3rd add instrcution
CY = 0
AC = 0
P = 1

Anyone explain to (i), (ii)
How can we get the instruction words and R8=?[hex]?
(i) instruction words[hex] is 0x4508, and R8= 0xF002
How can I get that?
(ii) instruction words[hex] is 0x4548 and R8=0x0002
How can I get that?
Consider the following instructions given in the table below. For each instruction determine its length (in words), the instruction words (in hexadecimal), source operand addressing mode, and the content of register R7 after execution of each instruction. Fill in the empty...

Compute the correct CPU computations and actions.
Write the final updated values for each memory, register and
flags after the given instruction executes in the space provided.
There are multiple parts of this problem.
Endianness: Check for endianness in case of loads and stores, in
each part of the question. If the question does not specify the
endianness, you can assume little-endian.
