The computer performance indicator measured by mips is computing speed. The full English name of mips is "Million Instructions Per Second", which represents the average execution speed of single-word fixed-point instructions and the million-level machine language instructions processed per second. Number is a measure of CPU speed.

The computer performance indicator measured by mips is the computing speed. MIPS is a measure of computer computing speed.
MIPS (Million Instructions Per Second): The abbreviation of Million Instructions Per Second, the average execution speed of single-word fixed-point instructions, the number of millions of machine language instructions processed per second. This is a measure of CPU speed. For example, an Intel80386 computer can process 3 million to 5 million machine language instructions per second, that is, we can say that 80386 is a 3 to 5 MIPS CPU. MIPS is just a measure of CPU performance.

MIPS is a very popular RISC processor in the world. MIPS means "Microprocessor without interlocked piped stages". Its mechanism is to use software methods to avoid data-related problems in the pipeline. It was first developed in the early 1980s by a research team led by Professor Hennessy of Stanford University. The R series of MIPS is a RISC industrial product microprocessor developed on this basis. These series of products are used by many computer companies to form various workstations and computer systems.
MIPS Technology is a well-known chip design company in the United States. It uses reduced instruction system computing architecture (RISC) to design chips. Compared with the Complex Instruction System Computing Structure (CISC) adopted by Intel, RISC has the advantages of simpler design and shorter design cycle, and can apply more advanced technologies to develop faster next-generation processors. MIPS is one of the earliest commercial RISC architecture chips. The new architecture integrates all the original MIPS instruction sets and adds many more powerful functions.
MIPS processor was a hot topic in RISC CPU design in the mid-1980s. MIPS is the best-selling RISC CPU, and you can see MIPS products on sale everywhere from Sony, Nintendo game consoles, Cisco routers and SGI supercomputers. As the RISC architecture competes with x86 chips, MIPS may be the only original RISC CPU design to be profitable this century. Compared with Intel, MIPS's licensing fees are relatively low, and it is used by most chip manufacturers except Intel.
The system structure and design concept of MIPS are relatively advanced. Its instruction system has been developed through the general processor instruction system MIPS I, MIPS II, MIPS III, MIPS IV to MIPS V, and the embedded instruction system MIPS16, MIPS32 to MIPS64. The development has been very mature. In terms of design concept, MIPS emphasizes the collaboration between software and hardware to improve performance while simplifying hardware design.
China Loongson 2 and its previous generation products use the 64-bit MIPS instruction architecture, which is incompatible with the commonly known X86 instruction architecture. The MIPS instruction architecture was created by MIPS Company and belongs to the RISC system. In the past, MIPS architecture products were mostly seen in the field of workstations. The "Emotion Engine" used in Sony's PS2 game console also uses MIPS instructions. The performance of these MIPS processors is very powerful. Loongson 2 also belongs to this camp. In terms of software, it is similar to the above products. Fully compatible.
