This article mainly introduces "what performance indicators do microcomputers have". In daily operation, I believe that many people have doubts about what performance indicators microcomputers have. The editor has consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts about "what performance indicators do microcomputers have?" Next, please follow the editor to study!

The main performance indicators of a microcomputer are: 1, operation speed, which refers to the number of instructions that can be executed per second; 2, main frequency; 3, word length, which refers to the number of bits of binary data that can be processed by computer computing units at the same time; 4, the capacity of internal memory; 5, the capacity of external memory; 6, access cycle; 7, the speed of Imax O; 8, performance-to-price ratio.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

Microcomputer is referred to as "microcomputer" and "microcomputer" for short. Because it has some functions of human brain, it is also called "microcomputer". A microcomputer is a small electronic computer composed of large-scale integrated circuits. It is a bare metal based on microprocessor, equipped with internal memory, input and output interface circuit and corresponding auxiliary circuit.

The main performance index of microcomputer

1. Operation speed

The so-called computer operation speed (average operation speed) refers to the number of instructions that can be executed per second, which is generally described as "millions of instructions per second" (mips,Million Instruction Per Second).

2. Main frequency

Microcomputer generally uses the main frequency to describe the operation speed, for example, the main frequency of Pentium/133 is 133 MHz, and the main frequency of Pentium 4 1.5G is 1.5 GHz. Generally speaking, the higher the dominant frequency, the faster the operation speed.

3. Word length

Word length refers to the number of bits of binary data that can be processed by computer computing units at the same time. The longer the word length, the higher the accuracy of the computer if it is used to store data, and the stronger the processing power of the computer is if it is used as a storage instruction. Usually the word length is always an integral multiple of 8, such as 8, 16, 32, 64 bits, and so on. Both Intel 486 and Pentium 4 are 32-bit machines.

At the same time, the larger the word length, the faster the computer can process the data and the higher the accuracy.

4. Capacity of internal memory

Internal memory, also referred to as main memory, is a memory that can be accessed directly by CPU. The programs to be executed and the data to be processed are stored in main memory. The size of the internal memory capacity reflects the computer's ability to store information in real time. The larger the memory capacity, the more powerful the system function and the larger the amount of data that can be processed.

5. Capacity of external memory

External storage capacity usually refers to the hard disk capacity (including internal and removable hard drives). The larger the external memory capacity, the more information can be stored, and the more applications can be installed.

6. Access cycle

The information code is stored in the memory, which is called "writing", and the information code is taken out of the memory, which is called "read". The time it takes for a memory to perform a "read" or "write" operation is called the memory access time (or read-write time). The minimum time required to start two independent "read" or "write" operations (such as two consecutive "read" operations) is called the access cycle.

7. The speed of Icano

The speed of the host IPUBO depends on the design of the IPUP O bus. This has little to do with slow devices (such as keyboards, printers), but has a significant effect on high-speed devices.

8. performance-to-price ratio

The full name of the performance-price ratio is the performance-price ratio, and the formula is: performance-price ratio = performance / price. Performance-to-price ratio should be based on your product performance requirements, should first meet the performance requirements, and then see whether the price is appropriate.

At this point, the study of "what are the performance indicators of microcomputers" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
