Xiaobian to share with you what the complete function of the calculator is to run, I believe most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article. Let's learn about it!

The complete function of an arithmetic unit is to perform arithmetic and logic operations; an arithmetic unit is a part of a computer that performs various arithmetic and logic operations; the basic operation of an arithmetic unit includes four operations of addition, subtraction, multiplication and division, and logic operations such as and, OR, no, XOR, and shift, comparison and transmission, also known as arithmetic logic components.

The complete function of the arithmetic unit is to perform arithmetic and logical operations.

Arithmetic unit: arithmetic unit, the part of a computer that performs various arithmetic and logical operations. The basic operation of the arithmetic unit includes addition, subtraction, multiplication and division, logic operations such as and, OR, no, XOR, and shift, comparison and transmission, also known as arithmetic logic unit (ALU).

The arithmetic unit is composed of arithmetic logic unit (ALU), accumulator, state register, general register group and so on. The basic functions of arithmetic logic operation unit (ALU) are four operations of addition, subtraction, multiplication and division, logic operations such as and, OR, no, XOR, shift, complement and so on. When the computer is running, the operation and type of operation of the arithmetic unit are determined by the controller. The data processed by the arithmetic unit comes from the memory; the processed result data is usually sent back to the memory or temporarily stored in the arithmetic unit. Together with Control Unit, it forms the core part of CPU.

The basic function of the arithmetic unit is to complete the processing of all kinds of data, such as four arithmetic operations, and, OR, inverse and other logical operations, arithmetic and logic shift operations, compare numerical values, change symbols, calculate the address of main memory, and so on.

The registers in the arithmetic unit are used to temporarily store the data participating in the operation and the intermediate results of the operation. The corresponding components are also set up in the calculator to record the characteristics of the result of an operation, such as whether it is overflowed, the symbol bit of the result, whether the result is zero, and so on.

There are many types of calculators used by computers, and there are different classification methods when analyzed from different angles. From the representation of decimal point, it can be divided into fixed-point arithmetic unit and floating-point arithmetic unit. The fixed-point arithmetic unit can only do fixed-point number operation, which is characterized by the small range represented by the machine number, but the structure is relatively simple. The floating-point arithmetic unit has a strong function, which can operate not only on floating-point numbers but also on fixed-point numbers. the representation range of floating-point numbers is very large, but the structure is quite complex.

From the carry system, it is divided into binary arithmetic unit and decimal arithmetic unit. General computers use binary arithmetic unit. As computers are widely used in business and data processing, more and more machines expand the function of decimal operation, so that the arithmetic unit can complete both binary operation and decimal operation. The calculator in the computer needs to have the function to complete a variety of operations, so it is necessary to integrate all kinds of algorithms and design a complete operation unit.

The above is all the contents of the article "what does the complete function of the calculator run?" Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
