hi,
I want to learn some basic I made small 4 bit alu that do only 5 function
arithmetic function
adder
subtractor
logic function
and logic
or logic
nor logic
look the diagram if diagram look like correct then I would like to make complex circuit

A theoretical ALU of your design should look something like this...
The OR and NOR are not drawn but they should be similar to the AND function. If you study the 74LS181 pdf logic diagram and understand it well. The design would be much simpler and efficient.
