This article mainly introduces what the computer mips represents, the article is very detailed, has a certain reference value, interested friends must read it!

Mips refers to the "speed" of a computer. The computing speed of a computer usually refers to the number of addition instructions that can be executed per second, often expressed in millions of times per second (Million Instructions Per Second,MIPS).

The computing speed of a computer usually refers to the number of addition instructions that can be executed per second, often expressed in millions of times per second (Million Instructions Per Second,MIPS).

MIPS: the average execution speed of single-word fixed-point instructions, the number of millions of machine language instructions processed per second. This is an indicator of the speed of CPU. For example, an Intel80386 computer can process 3 to 5 million machine language instructions per second, that is, we can say that 80386 is 3 to 5MIPS CPU. MIPS is only a measure of CPU performance.

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.

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.
