MyNOR: Single board computer that uses a single NOR gate as its ALU
I wonder how this ALU works. From what I remember ALUs use lot of XOR gates because an adder is simply a network of XOR gates with carry propagation.<p>How could a NOR gate do one bit addition?<p>Add two bits  ...  XOR  ...  NOR<p>0 + 0 = 0...........0...........1<p>0 + 1 = 1...........1...........0<p>1 + 0 = 1...........1...........0<p>1 + 1 = 0...........0...........0
