Band diagramIn this paper an all-optical half adder has been designed on a 2D photonic crystal slab having air holes in a hexagonal lattice pattern. The working principal of the device is based on beam interference. Multi-mode interference based Pi phase shifter been used in this design. ...
Half-adder logic diagram A dataflow VHDL description for the one-bit half-adder that uses the two logic expressions is shown in Figure 6.41. Here, two expressions are placed in the architecture body (one expression for the Sum output on line 17, the second for the Cout output on line 18...
Half adder –Is a logic circuit that is used in computer circuits to allow the computer to “carry” numbers when it is performing mathematical operations (for example to perform the addition of 9 + 2, a single 10s unit must be “carried” from the ones column to the tens column). Figu...
6.14.3 One-Bit Half-Adder An important logic design created from the basic logic gates is the half-adder, shown in Figure 6.39, which has two inputs (A and B) and two outputs (Sum and Carry-Out (Cout)). This cell adds the two binary input numbers and produces sum and carry-out ...
