The arithmetic-logic unit (ALU) performs allarithmetic operations (addition, subtraction,multiplication, and division) and logic operations.Logic operations test various conditions encounteredduring processing and allow for different actions to betaken based on the results. The data required to performthe arithmetic and logical functions are inputs from thedesignated CPU registers and operands

An Arithmetic logic unit (ALU) is a digital circuit that performs arithmetic and logical operations. The ALU is a fundamental building block of the central processing unit (CPU) of a computer, and even the simplest microprocessors contain one for purposes such as maintaining timers.

Before the developement of micro-processers and micro-computers, a computer was divided into functional units, e.g. reader, punch, bulk memory etc. These were all "peripherals", gathered around and connected to a CPU. A CPU was a central processing unit, consisting of control, memory, instruction interpreter, input / output and ALU. The ALU or Arithmetic Logic Unit was the very heart of the computer. A simple ALU could add, negate, compare (which of two numbers is greater or are they equal,), shift left, shift right, increment or decrement. It could also cause the computer to jump to a different part of the program, rather than go on to the next instruction in strict sequence. Most important of all was the ability to make a conditional jump, changing the order in which instructions were executed only if ( perhaps if not ) some condition was true. A computer with an ALU like this could subtract, multiply or divide by following a short sequence of instructions, but it was time consuming. Today's ALU can do things like these by hardware, built in. In a modern computer, the ALU, a very powerful entity, is integrated inside the main computer chip. It performs all the above functions and many more besides.

  • Arithmetic, such as addition, subtraction, multiplication, or division.
  • Logic, such as or, and, or exclusive or.
  • Comparison, such as greater than, less than, equal, or not equal.
