hi all, i want to make a 4-bit ALU with logic gates only and i'm looking for a complete circuit diagram that can allow me to do so, till now i can't find anyone all the circuits i found are missing the reset and CLK buttons, does any one have the complete circuit for a 4-bit ALU ? , any help would be appreciated.

I have to implement 8 bit Alu.....but it should be a sequential circuits,,,,,confused ....Basically I would use registers to store the input data and output.

For our final year project in digital electronics, my partner and I built a 4-bit computer using the 74181 ALU. The DG Nova minicomputer also used this chip in its CPU.
