During the 1980s and 1990s, MIPS processors for personal, workstation, and server computers were used by many companies such as Digital Equipment Corporation, MIPS Computer Systems, NEC, Pyramid Technology, SiCortex, Siemens Nixdorf, Silicon Graphics, and Tandem Computers. Historically, video game consoles such as the Nintendo 64, Sony PlayStation, PlayStation 2, and PlayStation Portable used MIPS processors.
Both MIPS and the R2000 were introduced together in 1985.
Few smart cards use SmartMIPS. MIPS Digital Media eXtension (MDMX): Multimedia application accelerations that were common in the 1990s on RISC and CISC systems. MIPS-3D: Additional instructions for improving the performance of 3D graphics applications == Calling conventions == MIPS has had several calling conventions, especially on the 32-bit platform. The O32 ABI is the most commonly-used ABI, owing to its status as the original System V ABI for MIPS.
The ABI took shape in 1990 and was last updated in 1994.

Historically, video game consoles such as the Nintendo 64, Sony PlayStation, PlayStation 2, and PlayStation Portable used MIPS processors.
MIPS processors also used to be popular in supercomputers during the 1990s, but all such systems have dropped off the TOP500 list.
During the mid-1990s, many new 32-bit MIPS processors for embedded systems were MIPS II implementations because the introduction of the 64-bit MIPS III architecture in 1991 left MIPS II as the newest 32-bit MIPS architecture until MIPS32 was introduced in 1999. MIPS Computer Systems' R4000 microprocessor (1991) was the first MIPS III implementation.
The ABI took shape in 1990 and was last updated in 1994.
A 1995 conference came up with MIPS EABI, for which the 32-bit version was quite similar.
A derivative of the R5000 from Toshiba, the R5900, was used in Sony Computer Entertainment's Emotion Engine, which powered its PlayStation 2 game console. Announced on October 21, 1996 at the Microprocessor Forum 1996 alongside the MIPS Digital Media Extensions (MDMX) extension, MIPS V was designed to improve the performance of 3D graphics transformations.
On May 12, 1997, SGI announced the "H1" ("Beast") and "H2" ("Capitan") microprocessors.
The "H1" and "H2" projects were later combined and were eventually canceled in 1998.
While there have not been any MIPS V implementations, MIPS64 Release 1 (1999) was based on MIPS V and retains all of its features as an optional Coprocessor 1 (FPU) feature called Paired-Single. When MIPS Technologies was spun-out of Silicon Graphics in 1998, it refocused on the embedded market.

MIPS Computer Systems' R4000 microprocessor (1991) was the first MIPS III implementation.
The former was to have been the first MIPS V implementation, and was due to be introduced in the first half of 1999.
Both were introduced in 1999.
Revision 2 of the ASE was introduced in the second half of 2006.
MIPS32/MIPS64 Release 5 was announced on December 6, 2012.
As of April 2017, the current version of MIPS is MIPS32/64 Release 6.
Release 4 was skipped because the number four is perceived as unlucky in many Asian cultures. In December 2018, Wave Computing, the new owner of the MIPS architecture, announced that MIPS ISA would be open-sourced in a program dubbed the MIPS Open initiative.
The program was intended to open up access to the most recent versions of both the 32-bit and 64-bit designs making them available without any licensing or royalty fees as well as granting participants licenses to existing MIPS patents. In March 2019, one version of the architecture was made available under a royalty-free license, but later that year the program was shut down again. In March 2021, Wave Computing announced that the development of the MIPS architecture has ceased.
In March 2021, MIPS announced that the development of the MIPS architecture had ended as the company is making the transition to RISC-V. == History == The first version of the MIPS architecture was designed by MIPS Computer Systems for its R2000 microprocessor, the first MIPS implementation.
