The ALU operates in a 3-stage pipeline. All logic functions such as AND, OR, and SUM (summation) can be executed within a single stage of the pipeline. In order to achieve the high-speed operation of ...

In the result, we can obtain the circuit areas with 2/3-input xor gates and 2/3/4-input xor gates. We provide an example with AES. Run 'main.py' directly, and we can obtain the circuit with 243 GE.

The same interferometric device shown in Fig. 2 was also used to perform the XOR logic function which makes use of destructive interference caused by an ″S″ shaped curve (two half circles with 50 nm ...
