This effect is defined as the change in the refractive index of a material due to the applied optical intensity [50,51]. Using different nonlinear materials assists one to guide the optical waves toward the desired output ports based on the optical intensity. The first all-optical full-adder...
The output is a signed fixed-point integer that is 2 bits long. The block has one input and one output. The Xilinx Time Division Demultiplexer block accepts input serially and presents it to multiple outputs at a slower rate. The Xilinx Time Division Multiplexer block multiplexes values ...
(a) General adder. (b) Full adder of two 1-bit words. Binary Adders 133 expense of other measures, such as power consumption (using advanced Schottky, for example, versus low-power Schottky designs). But for the logic de- signer, the important question is how to design an adder to ...
Full-Adder, Half-Subtractor, and Comparator One-Bit. The operation principle of these combinational logic functions is based on the constructive and destructive interferences between the input signal(s) and control signal. Numerical simulations show that a transmission threshold exists (0.25) which allo...
