一个 alu 具有各种输入和输出网络，它们用于在 alu 和外部电路之间传送数字信号。当 alu 工作时，外部电路在 alu 的输入端输入信号，而 alu 将产生运算结果，并将信号通过其输出端输出至外部电路。

An ALU is usually implemented either as a stand-alone integrated circuit (IC), such as the 74181, or as part of a more complex IC. In the latter case, an ALU is typically instantiated by synthesizing it from a description written in VHDL, Verilog or some other hardware description language.

What is an arithmetic-logic unit (ALU)? An arithmetic-logic unit is the part of a central processing unit that carries out arithmetic and logic operations on the operands in computer instruction words. In some processors, the ALU is divided into two units: …

Jul 5, 2020 · alu 是计算机的大脑，也是现代计算机的基石，基本上计算机所有的操作运算都会用到它。 ALU 有2单元，1个算术单元，1个逻辑单元，所以接下来分两块来分别介绍它们。

Apr 24, 2023 · Arithmetic logic unit (ALU) is defined as a circuit board embedded within a computer’s central processing unit (CPU), which performs mathematical and logical operations using gateways made of electrical transistors that can convey signals in 0s and 1s.

Jul 25, 2024 · In this tutorial, we’re going to look at how the arithmetic logic unit (ALU) works and how computers calculate through the ALU. We’ll also use logic gates to build a simple ALU. 2.

Today we're going to talk about a fundamental part of all modern computers. The thing that basically everything else uses - the Arithmetic and Logic Unit (or...

Mar 22, 2017 · The ALU is the mathematical brain of a computer. When you understand an ALU's design and function, you'll understand a fundamental part of modern computers.

Jan 1, 2003 · The arithmetic-logic unit (ALU) is that functional part of the digital computer that carries out arithmetic and logic operations on machine words that represent operands. It is usually a part of the central processing unit (CPU-- q.v .).

The Arithmetic Logic Unit (ALU) is a fundamental component of the CPU, executing arithmetic and logical operations crucial for computer functionality. It works in tandem with the Control Unit, which coordinates CPU activities.
