Web2. What you show is similar to the old AMD 2901 4-bit "bit-slice" ALU chip. You should be able to cascade them to any length, but longer equals slower because of the carry chain. You will need an AND gate to combine the "zero" flags. You can take the "carry", "sign" and "overflow" flags from the most-significant chip.
