Structural Verilog Implementation for the ALU in Computer Architecture. The ALU does the following operations:

• Adding two 4-bit numbers.
• Subtracting two 4-bit numbers.
• Adding 1 to a 4-bit number.
• Subtracting 1 from a 4-bit number.
• Bitwise ANDing two 4-bit numbers.
• Bitwise ORing two 4-bit numbers.
• Bitwise XORing two 4-bit numbers.
• Bitwise NOTing a 4-bit number.
• Arithmetic shifting right of a 4-bit number.
• no change.

Project is done for the Computer Architecture course in FCAI-CU as a team project.

• ALU

• Multiplixers, rightshift, ALU and main mudules are implemented by my colleague, Mohammed Adel.
