# What is the Full Form of ALU (Computer & Tech) – ALU Full Form

Today we Discuss About ALU Full Form in Cloud, But we gave all Information of A.L.U Related to Computer, CPU, Technology etc. All Full Forms with ALU History and Infection Details.

 A Arithmetic L Logic U Unit Do you want to know what is ALU, want complete information about ALU, then definitely read this article of ours till the end, because in this article we will give you ALU. Ale. You. Will give all the related information.

Friends, you must know that there are many parts of the computer, out of which one part works like the brain of the computer. And that part is called LU, today we are going to tell you about that part in English.

All of you must be aware of what a computer is, there is a part in it, which we call ALU. Let us first tell you about the full form of ALU.

## What is ALU?

The Arithmetic and Logical Unit is like a digital circuit inside the block of the Central Processing Unit (CPU), whose job is to perform arithmetic processing in a computer.

Inside it is a digital circuit, which is used to perform arithmetic and irrational processes. It is a part of a computer, which is located inside the block of CPU.

In this new age, there is a very powerful AI inside the CPU. Ale. You. have started coming. Today almost every computer’s CPU has AI. Ale. You. Apart from this also comes a CU ie Control Unit.

ALU C. P. U. It is that part of the computer that completes every arithmetic operation of the computer.

You must know that, CPU manages all the software and hardware inside a computer, and ALU helps CPU in this work.

The CPU consists of three essential units.

• ALU (Arithmetic Control Unit) , which is a module that handles all the calculations.
• CU (Control Unit) is a module that sees how resources are communicating with each other.
• MU (Memory Unit) , this module provides the recent recent memory when needed and also manages the external memory devices connected to the system.

The LU acts as the brain of this setup, as the CU and MU command the LU, and store and move the data, where calculations and other operations take place.

### How does ALU work?

LU solves basic arithmetic and logical problems. Arithmetic operations such as subtraction, multiplication and division, etc., logic operations such as operations on values, and values ​​such as OR.

Every information in a computer is stored in a binary count, which means that this count is written only in 0’s and 1’s.

In this transistor switch is used to calculate numbers, because there are only two possible paths in a switch, which are called open or close.

First is the open transistor, in which no current flows and it represents 0. Second comes the closed transistor, in which current flows through and it represents a 1.

Operation is also accomplished by connecting several transistors in it and one transistor can also be used to control the other.

In fact, the transistor switch has to be turned on or off depending on the placement of other transistors. It is shown as a gate, because the system is used to allow or stop the flow of current.

The easiest operation in this is the NOT gate. It uses a single transistor and has only one input and one output.

Most of these operations happen in ALU .

Addition: A and B are combined and the sum comes to Y and layout.

Adding with Carry: Adding up A, B and Carry and the sum is Y and Carry-out.

Subtract: B and A, or vice versa, are subtracted and the difference Y is brought to the layout.

To perform this function, there is a lending signal to the carry-out efficiency. This operation can also be used to inverse the magnitudes of A and B.

In such a case, the Y output, but also the processor, may be ignored, which consists only of the special state bits that we get from the operation.

Subtract with borrowing: Borrowing to B means that B can be subtracted with carry-in, it can also be done vice versa and the difference comes to Y and carry-out.

Negative (two’s complement): A (or B) is subtracted from zero and the difference is Y.

Growth: There is a growth in A (or B) and the result value is Y.

Subtraction: One of A (or B) is subtracted and the result value is Y.

Pass through. All bits of A (or B) appear to be Y unchanged. This operation is usually used to find the correspondence status of the operand or whether it is zero or negative or to insert the operand into the processor register.

### What is the ALU made of ? ALU Full Form

ALU consists of combinatorial circuits and it performs basic functions such as addition, subtraction and bitwise operation which is an action that is “directly supported by the CPU” and a combinatorial circuit means a circuit that has more than one component. Made by mixing.

LU cannot do sums of multiplication, because multiplication is impossible with the help of combinatorial circuits.

ALU is a very complex chipset that takes some inputs and selections, and performs an operation with the help of data and gives its answer as output.

The circuit of the LU performs the same type of operation as is required in the system. Mostly, a computer’s LU supports many operations, ranging from simple math operations to performing complex logical and relational functions.

### How are ALUs designed?

The ALU design depends on the transistor. True or False is shown on the computer screen when the transistor is turned on or off. All transistors are interconnected. It has a total of six gates.

1. OR GATE: OR gate has two transistors which are parallel connected. It consists of two inputs A and B, which are given on separate transistors.

The collector connects the two transistors together. If one of the collectors comes out by writing true, then the output also gets true, this is the logic of the OR gate.

2. AND GATE: In AND gate, two transistors are made by connecting them in serial. When input A is true, then transistor A is turned on and when the emitter of transistor B receives a high voltage, that is, true and gives true output.

If one of the transistors gets a false, then the transistor connected to it will also get off and your output will fall.

3.NOT GATE: NOT gate can be designed with only one transistor. For NOT gate the output is taken from collector not emitter.

4. ADDER: In this, the design of adder comes out of transistor, that is why adder is always made with the help of logic gate in ALU.

5. SUM: SUM or output in adder is same as NOR gate. For this reason the SUM circuit or design is connected in parallel to the SUM gate and the NOR gate.

And the carry output follows the pattern of AND gate. Hence the carry circuit is designed according to the AND gate.

6. OR GATE: The difference of OR gate follows the pattern of X-OR gate and one of the inputs for borrow output is inverted and sent to AND gate with the other input.

In this way we can design circuits of difficult operation from different basic logic gates. LUs have similar circuit designs, which solve arithmetic and logical operations.
