Aritmeetikaloogikaüksus

Aritmeetikaloogikaüksus, commonly known as the ALU, is a fundamental digital circuit within a computer's central processing unit (CPU). Its primary role is to perform arithmetic and logic operations on binary numbers. Arithmetic operations include addition, subtraction, multiplication, and division, while logic operations involve Boolean functions like AND, OR, NOT, and XOR. The ALU receives data from memory or registers and operates on it based on instructions from the control unit. After computation, the results are typically stored back in registers or sent to memory. The speed and efficiency of the ALU significantly impact the overall performance of the CPU and, consequently, the computer. Modern ALUs are highly complex and can perform multiple operations simultaneously, contributing to the rapid processing capabilities of contemporary devices. Understanding the ALU is key to grasping how computers execute instructions and process information.
