This article will explain in detail what mips refers to in the computer. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Mips in computer refers to the average execution speed of single-word long fixed-point instructions, that is, the number of millions of machine language instructions processed per second, which is an index to measure the speed of computer operation. MIPS is the rate at which instructions are executed, which specifies that performance is inversely proportional to execution time. The faster the computer, the higher the MIPS value.

MIPS is the abbreviation for Million Instructions Per Second-the number of millions of instructions executed by the computer per second. It is an index to measure the speed of a computer.

Nowadays, the frequency of CPU is getting higher and higher, and it is pipelined, superscalar and multi-core. It is no longer scientific to measure computer speed by clock frequency, but it is relatively reasonable to use MIPS to measure computer speed. MIPS is the rate at which instructions are executed, which specifies that performance is inversely proportional to execution time. The faster the computer, the higher the MIPS value.

The recommended maximum operating frequency of S3C44B0X with ARM7 as its kernel is 66MHz. According to the technical data provided by ARM Company, the computing speed of Cortex A9 CPU can be calculated according to the following formula: MIPS=0.9 × MHz. From this, it can be obtained that the maximum operating speed of the old Arm 7 series S3C44B0X is about 0.9 × 66MHz=59.4MIPS. The 51 single chip microcomputer of 6m usually takes 12 or 24 clock cycles to complete one instruction, and the multiplication and division instructions need 48 clock cycles. In this way, I preliminarily estimate that the operation speed of 6m 51 single-chip microcomputer should be between 0.2~0.5MIPS. It can be seen that there is a huge difference in computing speed between 8-bit and 32-bit computers.

Taking AVR as an example, its data throughput can reach 1MIPS/MHz, that is, the oscillation frequency of 1MHz can reach 1MIPS.

To sum up, using MIPS to measure computer speed is very reasonable, for different cpu, its maximum working frequency is different, data throughput is also different, so it can not be generalized.

On the computer mips refers to what is shared here, I hope that 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.
