Adder-subtractor 一、问题描述 An adder-subtractor can be built from an adder by optionally negating one of the inputs, which is equivalent to inverting the input then adding 1. The net result is a circuit that can do two operations: (a + b + 0) and (a + ~b + 1). See Wikipedia ...

Note that this flop is enabled only when mode is 1 or 2 and not for other values. Output q is fed back through an adder and subtractor block into the input of the same flop through a mux which is again controlled by mode .Consider the same design from above with a 1-bit mode ....
