What is ALU short answer?
An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer. Modern CPUs contain very powerful and complex ALUs. In addition to ALUs, modern CPUs contain a control unit (CU).
What is ALU and RAM?
(Arithmetic Logic Unit) The high-speed circuit in the CPU that does the calculating and comparing. Numbers are transferred from RAM (memory) into the ALU for calculation, and the results are sent back to RAM. Alphanumeric data are sent from RAM into the ALU for comparing.
What is between ALU and CPU?
The difference between ALU and CPU is that ALU is an electronic circuit, which is a subsystem of CPU that performs arithmetic and logical operations while a CPU is an electronic circuit that handles instructions to operate the computer.
What is difference between ALU and Mu?
ALU stands for Arithmetic Logic Unit. MU- Memory Unit, the primary memory for holding data. CU- Control Unit, for controlling tranfer/requests between other units.
What is an ALU size?
The size of input quantities of ALU is often referred to as word length of the computer. Many processors today have word length of 32 and 64 bit. Processing unit also includes a set of registers for temporary storage of data and memory addressing.
What does ALU stand for in a computer?
ALU stands for the Arithmetic Logical Unit. It is the main functional component of the CPU that is responsible for conducting all the mathematical calculations and logical operations. The data given as input to the computers is manipulated and processed by ALU on the basic of instructions and directions provided by CU.
What is the function of Alu in computer?
An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer.
What is the full form of Alu in computer?
Arithmetic Logic Unit (ALU): A subunit within a computer’s central processing unit. ALU 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.
What is the function of Alu in a microprocesser system?
An arithmetic logic unit (ALU) is a major component of the central processing unit of the a computer system. It does all processes related to arithmetic and logic operations that need to be done on instruction words. In some microprocessor architectures, the ALU is divided into the arithmetic unit (AU) and the logic unit (LU).
