Question

write a short note on ALU (arithmetic logic unit)

Answer 1

                          Short note on ALU {arithmetic logic unit}

1.
 An arithmetic logic unit (ALU) represents the fundamental building block of the central processing unit of a computer. An ALU is a digital circuit used to perform arithmetic and logic operations.

2.
 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).

3.
Most of the operations of a CPU are performed by one or more ALUs, which load data from input registers. A register is a small amount of storage available as part of a CPU.

4.
The control unit tells the ALU what operation to perform on that data, and the ALU stores the result in an output register. The control unit moves the data between these registers, the ALU, and memory.

Answer 2

A digital circuit that performs arithmetic and logic operations is known as an arithmetic logic unit (ALU).

• It is the most essential component of a computer's central processing unit (CPU).
• ALUs on modern CPUs are extremely powerful and sophisticated. Modern CPUs have a control unit in addition to ALUs (CU).
• One or more ALUs load data from input registers to accomplish the majority of a CPU's operations. A register is a little piece of storage that comes with a CPU.
• The control unit instructs the ALU on how to process the data, and the ALU saves the result in an output register. The data is moved between these registers, the ALU, and memory by the control unit.
