Computer Organization | ALU and Data PathRepresenting and storing numbers were the basic of operation of the computers of earlier times. The real go came when computation, manipulating numbers like adding, multiplying came into picture. These operations are handled by computer’s arithmetic logic unit (ALU). The ALU is the mathematical brain of a computer. The first ALU was INTEL 74181 implemented as a 7400 series is a TTL integrated circuit which was released in 1970.The ALU is a digital circuit that provides arithmetic and logic operation. It is the fundamental building block of central processing unit of a computer. A modern CPU has very powerful ALU and it is complex in design. In addition to ALU modern CPU contains control unit and set of registers. Most of the operations are performed by one or more ALU’s, which load data from input register. Registers are a small amount of storage available to CPU. These registers can be accessed very fast. The control unit tells ALU what operation to perform on the available data. After calculation/manipulation the ALU stores the output in an output register.
