Computer Logical Organization 简明教程
Logic Gates
逻辑门是任何数字系统的基本构件。它是一个电子电路,具有一个或多个输入,但只有一个输出。输入和输出之间的关系基于一个 certain logic 。基于此,逻辑门被命名为 AND 门、OR 门、NOT 门等等。
Logic gates are the basic building blocks of any digital system. It is an electronic circuit having one or more than one input and only one output. The relationship between the input and the output is based on a certain logic. Based on this, logic gates are named as AND gate, OR gate, NOT gate etc.
AND Gate
一个执行 AND 操作的电路如图所示。它有 n 个输入 (n >= 2) 和一个输出。
A circuit which performs an AND operation is shown in figure. It has n input (n >= 2) and one output.
OR Gate
一个执行 OR 操作的电路如图所示。它有 n 个输入 (n >= 2) 和一个输出。
A circuit which performs an OR operation is shown in figure. It has n input (n >= 2) and one output.
NOT Gate
NOT 门也称为 Inverter 。它有一个输入 A 和一个输出 Y。
NOT gate is also known as Inverter. It has one input A and one output Y.
NAND Gate
NOT-AND 操作称为 NAND 操作。它有 n 个输入 (n >= 2) 和一个输出。
A NOT-AND operation is known as NAND operation. It has n input (n >= 2) and one output.
NOR Gate
NOT-OR 操作称为 NOR 操作。它有 n 个输入 (n >= 2) 和一个输出。
A NOT-OR operation is known as NOR operation. It has n input (n >= 2) and one output.
XOR Gate
XOR 或 Ex-OR 门是一种特殊类型的门。它可用在半加法器、全加法器和减法器中。异或门缩写为 EX-OR 门或有时为 X-OR 门。它有 n 个输入 (n >= 2) 和一个输出。
XOR or Ex-OR gate is a special type of gate. It can be used in the half adder, full adder and subtractor. The exclusive-OR gate is abbreviated as EX-OR gate or sometime as X-OR gate. It has n input (n >= 2) and one output.
XNOR Gate
XNOR 门是一种特殊类型的门。它可用在半加法器、全加法器和减法器中。异或非门缩写为 EX-NOR 门或有时为 X-NOR 门。它有 n 个输入 (n >= 2) 和一个输出。
XNOR gate is a special type of gate. It can be used in the half adder, full adder and subtractor. The exclusive-NOR gate is abbreviated as EX-NOR gate or sometime as X-NOR gate. It has n input (n >= 2) and one output.
