• Here is the final code for the ALU project with the different components brought together.
• To run this on your own machines, create a project named ALU and download these files into the project folder.

Inputs: 2 16-bit numbers in 2’s complement form (A, B), Control bits (S0, S1)

• Signed Addition (control input S1S0 = 00)
• Subtraction (Control input S1S0 = 01)
• NAND operation (control input S1S0 = 10)
• XOR operation (control input S1S0 = 11)

Outputs: 1 16-bit number (R), 1 carry bit (C), 1 zero bit (Z)

Note: For arithmetic operations; we used Kogge Stone Adder

The result is 17-bit in 2’s complement form (with carry bit as MSB concatenated by result bits (R))
