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.

Dec 28, 2024 · An Arithmetic Logic Unit (ALU) is a key component of the CPU responsible for performing arithmetic and logical operations. The collection of functional units like ALUs, registers, and buses that move data within the processor. together are known as Data Path, they execute instructions and manipulate data during processing tasks.

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: an arithmetic unit (AU) and a logic unit (LU).

The Arithmetic Logic Unit (ALU) is the heart of any CPU. An ALU performs three kinds of operations, i.e. Arithmetic operations such as Addition/Subtraction, Logical operations such as AND, OR, etc. and; Data movement operations such as Load and Store; ALU derives its name because it performs arithmetic and logical operations.

May 15, 2024 · Discover how the Arithmetic Logic Unit (ALU) in a CPU performs essential arithmetic and logical operations, powering the efficiency of modern computing systems.

Apr 24, 2023 · Arithmetic logic unit (ALU) is 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 · The logic unit handles logical operations like AND, OR, and XOR, instead of arithmetic operations. It also performs numerical tests. For example, it checks whether the number is negative or not.

Arithmetic Logic Unit (ALU) Example ALU: given inputs a and b, and an operation code, produce output. Operation code: 000: AND 001: OR 010: NOR 011: ADD 111: SUB How do we implement this ALU?

Consider an ALU is having four arithmetic operations - Addition, subtraction, multiplication and division. Also consider that the ALU is having four logical operations: OR, AND, NOT & EX-OR. We need three control lines to identify any one of these operations. The input combination of these control lines are shown below:
