XOR gate (sometimes EOR, or EXOR and pronounced as Exclusive OR) is a digital logic gate that gives a true (1 or HIGH) output when the number of true inputs is odd. An XOR gate implements an exclusive or from mathematical logic; that is, a true output results if one, and only one, of the inputs to the gate is true. If both inputs are false (0 ...
OAI-gates can efficiently be implemented as complex gates. An example of a 3-1 OAI-gate is shown in the figure below. ... Implementation of an XOR gate using a 2-2 ...
In logical circuits, a simple adder can be made with an XOR gate to add the numbers, and a series of AND, OR and NOT gates to create the carry output. On some computer architectures, it is more efficient to store a zero in a register by XOR-ing the register with itself (bits XOR-ed with themselves are always zero) than to load and store the ...
The XOR gate is dependent on timing. The logic OR gate is simple to make in dominoes, consisting of two domino paths in a Y-shape with the stem of the Y as the output. The complex piece is which gate is able to be added to OR to obtain a functionally complete set such that all logic gates can be represented.
A logic circuit diagram for a 4-bit carry lookahead binary adder design using only the AND, OR, and XOR logic gates.. A logic gate is a device that performs a Boolean function, a logical operation performed on one or more binary inputs that produces a single binary output.
There are essentially seven basic logic functions implemented as logic gates: AND, OR, NOT, NAND, NOR, XOR and XNOR. A chaotic morphing logic gate consists of a generic nonlinear circuit that exhibits chaotic dynamics producing various patterns. A control mechanism is used to select patterns that correspond to different logic gates.
The XOR gate built from NOR gates in the table is the one which, according to the XOR gate article, "offers the advantage of a shorter propagation delay": Whereas the XNOR gate built from NAND gates in the table was originally the one which, according to the XNOR gate article, actually has more propagation delay:
XOR has the worst-case Karnaugh map—if implemented from simple gates, it requires more transistors than any other function. Back when transistors were more expensive, designers of the Z80 and many other chips were motivated to save a few transistors by implementing the XOR using pass-transistor logic rather than simple gates.
