The Arithmetic Logic Unit Alu

An arithmetic logic unit alu is a major component of the central processing unit of a computer system.
The arithmetic logic unit alu. In addition to alus modern cpus contain a control unit cu. Other articles where arithmetic logic unit is discussed. Short for arithmetic logic unit the alu is a complex digital circuit. One of many components within a computer s central processing unit it performs both bitwise and mathematical operations on binary numbers and is the last component to perform calculations in the processor.
An arithmetic logic unit alu is the part of a computer processor that carries out arithmetic and logic operations on the operands in computer instruction words. Modern cpus contain very powerful and complex alus. The alu performs simple addition subtraction multiplication division and logic operations such as or and and. In some microprocessor architectures the alu is divided into the arithmetic unit au and the logic unit lu.
It is a fundamental building block of many types of computing circuits including the central processing unit cpu of computers fpus and. In some processors the alu is divided into two units an arithmetic unit au and a logic unit lu. It does all processes related to arithmetic and logic operations that need to be done on instruction words. The alu uses operands and code that tells it which operations to perform for input data.
A sub unit within a computer s central processing unit. Of a control unit an arithmetic logic unit alu a memory unit and input output i o controllers. It represents the fundamental building block of the central processing unit cpu of a computer. In some microprocessor architectures the alu is divided into the arithmetic unit au and the logic unit lu.
Alu contains the logical circuit to perform mathematical operations like subtraction addition multiplication division logical operations and logical shifts on the values held in the processors registers or its accumulator. This is in contrast to a floating point unit fpu which operates on floating point numbers. Alu full form is arithmetic logic unit takes the data from memory registers. It does all processes related to arithmetic and logic operations that need to be done on instruction words.
The memory stores the program s instructions and data. An arithmetic logic unit alu is a digital circuit used to perform arithmetic and logic operations.
