This article will explain in detail whether the number of registers in the calculator has nothing to do with the speed of the system, and the content of the article is of high quality, so the editor will share it for you as a reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

The number of registers in the arithmetic unit is related to the running speed of the system. The arithmetic unit is composed of arithmetic logic unit, accumulator, state register, general register group and so on. Registers are some small storage areas used to store data in CPU, which are used to temporarily store the data and results of the operation.

Arithmetic unit

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 processing object of the arithmetic unit is data, so the data length and the method of computer data representation have a great influence on the performance of the arithmetic unit. In the 1970s, microprocessors often used 1, 4, 8, 16 binary bits as the basic unit of data processing. Most general-purpose computers use 16, 32, and 64 bits as the length of data processed by the arithmetic unit. An arithmetic unit that can process all bits of a data at the same time is called a parallel arithmetic unit. If only one bit is processed at a time, it is called a serial arithmetic unit. Some operators can handle several bits at a time (usually 6 or 8 bits), and a complete data is divided into several segments for calculation, which is called serial / parallel arithmetic unit. Arithmetic units tend to process data of only one length. Some can also handle several different lengths of data, such as half-length operation, double-length operation, quadruple-length operation and so on. Some data length can be specified in the process of operation, which is called variable word length operation.

According to the different representation of data, there can be binary arithmetic unit, decimal arithmetic unit, hexadecimal arithmetic unit, fixed-point integer arithmetic unit, fixed-point decimal arithmetic unit, floating-point number arithmetic unit, and so on. According to the nature of the data, there are address operators, character operators and so on.

Its main function is to carry out arithmetic and logical operations.

Register

Registers are some small storage areas used to store data in CPU, which are used to temporarily store the data and results involved in the operation. In fact, register is a commonly used sequential logic circuit, but this sequential logic circuit only contains storage circuits. The storage circuit of registers is composed of latches or flip-flops. Because a latch or flip-flop can store 1-bit binary numbers, N-bit registers can be formed by N latches or flip-flops. Registers are part of the CPU. Registers are high-speed storage components with limited storage capacity, which can be used to temporarily store instructions, data, and addresses.

In the computer field, registers are internal components of CPU, including general registers, special registers and control registers. Registers have a very high read and write speed, so data transfer between registers is very fast.

About whether the number of registers in the calculator has nothing to do with the speed of the system is shared here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
