MIPS architecture

technology Maturity 7-9 Next article →

MIPS is a special set of rules for computer chips. These rules are called an instruction set architecture, or ISA. This architecture tells a processor how to follow commands and handle data. It is part of a group called RISC, which stands for reduced instruction set computer.

MIPS is important because it helped many machines work very fast. It also helped shape how other modern computer chips are designed today.

Inside a MIPS chip, the work happens using different parts. The main part uses registers to hold information. A register is like a small, fast storage spot for numbers.

MIPS is a load/store architecture. This means the chip only moves data between memory and registers using specific load and store commands. Most other math happens directly between the registers. The chip also uses coprocessors, which are extra helpers. For example, one helper can do math for 3D graphics. This makes moving shapes in a video game much smoother.

Scientists and engineers first created MIPS in 1985. It was made by a company called MIPS Computer Systems.

They designed it for their first chip, the R2000. Later, they made many different versions like MIPS II and MIPS III. In 1991, they released the MIPS III architecture. This version was used in many different types of computers. The company later became MIPS Technologies, Inc. based in the United States.

There are many interesting facts about the MIPS family. Early versions used 32-bit math, but 64-bit versions came later.

One famous version was used in the Nintendo 64 game console. Another version helped power the Sony PlayStation 2. In 1999, new versions called MIPS32 and MIPS64 were introduced. Interestingly, the company skipped a "Release 4" update. They did this because the number four is seen as unlucky in some Asian cultures. As of April 2017, the current version was Release 6.

You might see MIPS working in things you use every day. It has been used in supercomputers and workstations.

It even worked in embedded systems, which are small computers inside other machines. Many students in universities study MIPS to learn how computers work. In March 2021, the company announced it would stop making new MIPS designs. They are now moving toward a new system called RISC-V. Even so, some companies still use MIPS to make their own special chips.
