An Arithmetic Logic Unit that includes first multiplexers coupled to a first adder, the first multiplexers controlled by a first opcode register; second multiplexers receiving input from the first adder and coupled to a second adder; and a second opcode register for controlling one or more of the second multiplexers, the first adder, or the second adder. A combination of the bits in the first and second opcode registers configures the ALU to perform one or more arithmetic operations or one or more logic operations or any combination thereof.
