Difference between ALU and CPU

Main Difference between ALU and CPU

A computer is completed when many components come together to form a device, each of which has its own meaning and the way in which they make things happen. The two most important parts that are covered in this article are CPU and ALU, they are known as Central Processing Unit and Arithmetic Logical Unit. The former is responsible for all the activities that are performed on a device and is later called the heart of the computer. While the other is in charge of the logical and mathematical operations that occur within the system and causes certain instructions to be completed in the correct way.

ALU, which is more widely known as Arithmetic Logical Unit, is the main component of the central processing unit. The main job of this unit is to perform all the logical arithmetic operations, such as addition, subtraction, multiplication, division, and many others. It is considered the most dominant part of the CPU, and many of the original functions will start to work without it. In most modern computers, it is divided into two more parts; the first is the AU, which deals with arithmetic operations such as those mentioned above and the second is the LU, known as the logical unit that deals with the logical operations that define the subject. Many computers have more than one of these units and handle both fixed-point and floating-point operations at the same time. In home computers, most of the time this process has an appropriate chip called a numeric coprocessor. The data that comes its way is direct, as are the implemented instructions. The input is usually the instruction word that contains a mode of operation, more than one operand, and sometimes a format code is also present. The output, in this case, consists of a result that is placed in a storage register and has specific settings that indicate that the action was successful. A separate storage space is present within the system and has various other characteristics, such as giving negative values, performing operations on the numbers that are not complemented by logic, and many others. The input is usually the instruction word that contains a mode of operation, more than one operand, and sometimes a format code is also present. The output, in this case, consists of a result that is placed in a storage register and has specific settings that indicate that the action was successful. A separate storage space is present within the system and has various other characteristics, such as giving negative values, performing operations on the numbers that are not complemented by logic, and many others. The input is usually the instruction word that contains a mode of operation, more than one operand, and sometimes a format code is also present. The output, in this case, It consists of a result that is placed in a storage log and has specific settings that indicate that the action was successful. A separate storage space is present within the system and has various other characteristics, such as giving negative values, performing operations on the numbers that are not complemented by logic, and many others.

The CPU is the most important part of the computer and is known by many names such as processor, microprocessor, central processor, and others. It is the logic circuit that acts on the various activities that occur within the device and is called the heart of the computer. The steps involved are the same as the process mentioned above where the instruction that is fetched from the memory unit, then decoded to make it understandable to the computer, reading the instruction and then executing it becomes the next part. The essential elements that become part of the processor are the logical arithmetic unit that performs all arithmetic and logical operations, a floating point unit known as a mathematical coprocessor. The next part is called a register that contains all the instructions and other data and supplies it to the system when necessary. The last two parts are the L1 and L2 cache where its inclusion in the CPU saves time, and the data does not have to be entered over and over again. Most of the systems that exist in the world today have more than two processors to improve performance. This action helps in a way that when the computer has to work at faster speeds, although these are two separate processors, combining them in the same socket causes them to then run at speeds of a second. In the case of a personal computer, this term is used for a processing element contained within the single integrated circuit called an IC chip. The major vendors of these processors are known as Intel and AMD. Most of the systems that exist in the world today have more than two processors to improve performance. This action helps in a way that when the computer has to work at faster speeds, although these are two separate processors, combining them in the same socket causes them to then run at speeds of a second. In the case of a personal computer, this term is used for a processing element contained within the single integrated circuit called an IC chip. The major vendors of these processors are known as Intel and AMD. Most of the systems that exist in the world today have more than two processors to improve performance. This action helps in a way that when the computer has to work at faster speeds, although these are two separate processors, combining them in the same socket causes them to then run at speeds of a second. In the case of a personal computer, this term is used for a processing element contained within the single integrated circuit called an IC chip. The major vendors of these processors are known as Intel and AMD. This term is used for a processing element contained within the single integrated circuit called an IC chip. The major vendors of these processors are known as Intel and AMD. This term is used for a processing element contained within the single integrated circuit called an IC chip.

Differences in a nutshell

  1. The full name of the ALU is Arithmetic Logical Unit and the full name of the CPU is Central Processing Unit.
  2. The main task of ALU is to perform all the operations that relate to human logic and mathematics, while the main function of the central processing unit is to make sure that all functions are performed accurately on time.
  3. A logical arithmetic unit is part of the central processing unit.
  4. There may be one or more central processing units in a computer depending on the requirement, but there is only one
  5. Arithmetic logic unit in a central processing unit.
  6. A CPU was also known as a processor, it interprets and executes the basic instructions that operate a computer. An ALU performs basic calculations such as addition, subtraction, multiplication, and division.
  7. The core parts of the ALU include an arithmetic unit and a logical unit, while the main parts of the CPU include the logical arithmetic unit, the floating point unit, the register that contains all the instructions, and the L1 and L2 cache.

Conclusion

We hear a lot about these terms in our daily routines and therefore this article clarifies all the main functions, their operation and examples to make sure that everything is simplified for the reader and they get to know more about a central processing and arithmetic unit. . logical unit.
