It fetches internal instructions of the programs from the main memory to the processor instruction register, and based on this register contents, the control unit generates a control signal that supervises the execution of these instructions.

ALU full form is Arithmetic Logic Unit , takes the data from Memory registers ; 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. It is the size of the word that the ALU can handle which, more than any other measure, determines the word-size of a processor: that is, a bit processor is one with a bit ALU. After processing the instructions the result will store in Accumulator. Control unit generates control signals to ALU to perform specific operations. The accumulator is used as by default register for storing data.
The purpose of the CPU is to process data. The CPU is where processes such as calculating, sorting and searching take place. Whatever is done on our computers, such as checking emails, playing games and doing homework, the CPU has processed the data we use. The CPU is made up of three main components, the control unit , the immediate access store and the arithmetic and logic unit. The control unit controls the flow of data within the system.
5 Difference Between Arithmetic Logical Unit (ALU) And Control Unit (CU)
The term microprocessor typically refers to the central processing unit CPU of a microcomputer , containing the arithmetic logic unit ALU and the control units. It is typically implemented on a single LSI chip. This separates the "brains" of the operation from the other units of the computer. The microprocessor contains the arithmetic logic unit ALU and the control unit for a microcomputer.

Show all documents The maximum drain current produces by dual gate mode is much higher than single gate mode. All the results are carried out using H-spice simulation tool. The simulation of ALU is carried at 32nm technology. The figure of merit measured for ALU are power and delay.
The basis of comparison include: Description, dependency, function and design. It performs all processes related to arithmetic and logic operations that need to be done on instruction words. In some processors, the arithmetic logical unit is divided into two units, an arithmetic unit AU and a logic unit LU. The ALU is typically designed in such a way that it has a direct input and output access to the processor main memory —the random access memory RAM. Now, the input and outputs flow along an electronic path that is known as a bus.
The main function of the control unit is to fetch and execute instructions from the memory of a computer. It is included as a part of Von Neumann architecture developed by John Neumann. It is responsible for providing the timing signals, and control signals and directs the execution of a program by the CPU. It is included as an internal part of the CPU in modern computers. This article describes complete information about the control unit.
In computing , an arithmetic logic unit ALU is a combinational digital circuit that performs arithmetic and bitwise operations on integer binary numbers. It is a fundamental building block of many types of computing circuits, including the central processing unit CPU of computers, FPUs, and graphics processing units GPUs. The inputs to an ALU are the data to be operated on, called operands , and a code indicating the operation to be performed; the ALU's output is the result of the performed operation.
Arithmetic Logic Unit is the part of a computer that performs arithmetic operations on binary numbers. The inputs to an ALU are the data where we have to perform operations. They are called operands.
An error-correction method is proposed for computer arithmetic logic units, in which memory duplication is executed and an algebraic linear code with minimal information redundancy is used for control. Rules for the use of coded information have been formulated for error detection during execution of arithmetic and logical operations. A procedure is proposed for the formulation of the duplication channel of arithmetic logic units due to the use of equipment intended for coding of information and the functional redundancy of the arithmetic logic units of the processor.
