In computing, an arithmetic logic unit (ALU) is a combinational digital circuit that performs arithmetic and bitwise operations on integer binary numbers. [1][2] This is in contrast to a floating-point unit (FPU), which operates on floating point numbers.

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。

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: …

2024年12月28日 · The Arithmetic Logic Unit (ALU) is a crucial component of a computer's CPU, responsible for performing arithmetic and logical operations, and works in conjunction with registers and buses to facilitate data processing.

2024年5月15日 · An Arithmetic Logic Unit (ALU) is a critical component of a computer’s central processing unit (CPU) responsible for performing arithmetic and logical operations. It executes basic mathematical calculations like addition, subtraction, multiplication, and division, as well as logical operations such as AND, OR, NOT, and XOR.

2023年4月24日 · 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.

The Arithmetic Logic Unit (ALU) is the fundamental component in a computing system like a computer. It is basically the actual data processing element within the central processing unit (CPU) in a computing system. It performs all the arithmetic and logical operations and forms the backbone of modern computer technology.

2021年5月2日 · Short for Arithmetic Logic Unit, the ALU is a complex digital circuit with an AU (Arithmetic Unit) and a LU (Logic Unit). There are multiple Arithmetic Logic Units in a computer, including multiple ALUs in the CPU (Central Processing Unit), GPU (Graphics Processing Unit), and FPU (Floating-Point Unit).

What is ALU? ALU stands for Arithmetic Logic Unit. An ALU is a key component of the CPU which performs arithmetic and logical operations. It can perform billions of operations per second. An ALU circuit has the integration of four key components inputs, operands, outputs, and storage.

An arithmetic logic unit (ALU) is a key component of a computer’s central processor unit. The ALU performs all arithmetic and logic operations that must be performed on instruction words. The ALU is split into two parts in some microprocessor architectures: the AU and the LU.
