So I have the 8 inputs, x,y,zx,zy,nx,ny,f,no and the 3 outputs out, zr, ng. I don't know how to send the inputs to the outputs. Its difficult to explain. Does the ALU only perform one of these things at a time? what if it performs none of them? how do i send so many inputs to just 1 output?
Each pin named on the OUTPUT line is a physically separate signal; the ALU always outputs all three signals.
This is like DMux where both 'a' and 'b' outputs always have values.
