I have project i need your help.

this is the Project Description
In this project, you will design a complete arithmetic unit of a microprocessor which can
do addition, subtraction, multiplication, and division of two 2-bit binary numbers (A1A0
and B1B0). Using a 2x4 decoder whose inputs X1X0 will act as control inputs, you will
select the circuits within the arithmetic unit as following:
Decoder inputs
X1X0
Arithmetic
Circuit
Activated
00 Adder
01 Subtractor
10 Multiplier
11 Divider
Depending on the circuit activated and the A1A0 and B1B0 inputs of that circuit,
corresponding results will be produced by the arithmetic unit. For example,
¡ú if X1X0 = 00, adder circuit will be activated. Then if we supply A1A0 = 102 and B1B0 =
102, the adder circuit will output 1002 = 410 as the result.
(Hint: A1A0 + B1B0 = CS1S0 where C is the carry-out and S1, S0 represent sums)
¡ú if X1X0 = 01, subtractor circuit will be activated. Then if we supply A1A0 = 102 and B1B0
= 112, the subtractor output will be 1112s complement = ¨C110.
(Hint: A1A0 ¨C B1B0 = BD1D0 where B represents borrow and D1,D0 represent differences)
¡ú if X1X0 = 10, multiplier circuit will be activated. Then if we supply A1A0 = 102 and B1B0 =
112, the multiplier output will be 01102 = 610.
(Hint: A1A0 x B1B0 = P3P2P1P0 where P3,P2,P1,P0 represent product bits)
¡ú if X1X0 = 11, divider circuit will be activated. Then if we supply A1A0 = 102 and B1B0 =
112, the divider output will be 10002. The first two-bit in the result show that the
remainder is 102 and the last two-bits show that the quotient is 002.
(Hint: A1A0 ¡ B1B0 = R1R0Q1Q0 where R1,R0 represent remainder bits and Q1Q0 represent
quotient bits. For division 00/00, result will be displayed as 0000. For division 01/00 or
10/00 or 11/00, result ¡Þ (infinity) will be displayed as 1111)

There are many computer architecture references available that may help you.

However good the books are, you'll need a good background of digital logic, which I assume you are in the process of pursuing.

To design a complete arithmetic unit for a microprocessor that can perform addition, subtraction, multiplication, and division of two 2-bit binary numbers, you can follow these steps:

Step 1: Design the Adder Circuit
- Implement a 2-bit adder circuit that takes inputs A1A0 and B1B0 and produces the sum (S1, S0) as the output.
- Handle the carry-out (C) from the addition.

Step 2: Design the Subtractor Circuit
- Implement a 2-bit subtractor circuit that takes inputs A1A0 and B1B0 and produces the difference (D1, D0) as the output.
- Handle the borrow (B) from the subtraction.

Step 3: Design the Multiplier Circuit
- Implement a 2-bit multiplier circuit that takes inputs A1A0 and B1B0 and produces the product (P3, P2, P1, P0) as the output.

Step 4: Design the Divider Circuit
- Implement a 2-bit divider circuit that takes inputs A1A0 and B1B0 and produces the quotient (Q1, Q0) and remainder (R1, R0) as the output.

Step 5: Implement the 2x4 Decoder
- The decoder will take inputs X1X0 and activate the corresponding arithmetic circuit based on its control inputs.
- The decoder will activate the adder circuit if X1X0 = 00, the subtractor circuit if X1X0 = 01, the multiplier circuit if X1X0 = 10, and the divider circuit if X1X0 = 11.

Step 6: Connect the Inputs and Outputs
- Connect the A1A0 and B1B0 inputs to the selected arithmetic circuit based on the activation from the decoder.
- Depending on the selected circuit, observe the corresponding output (sum, difference, product, quotient, and remainder).

To test the arithmetic unit, you can provide specific inputs (A1A0 and B1B0) for each operation (addition, subtraction, multiplication, and division) and observe the output from the unit.

Note: The given hints provide formulas and representations for the various operations and their outputs. You need to implement the circuits and logic for these operations accordingly.
