MIPS Technologies, Inc., formerly MIPS Computer Systems, Inc., was a United States-based fabless semiconductor design company that is most widely known for developing the MIPS architecture and a series of RISC CPU chips based on it.〔John Gantz (October 14, 1991), MIPS will have a tough time in a crowded market, ''InfoWorld'', p. 137.〕〔Computer History Museum. “(John Hennessy: 2007 Fellow Awards Recipient ).” 2007.

Imagination Technologies is a UK-based company best known for their PowerVR graphic chips family.〔(【引用サイトリンク】title=Acquisition of MIPS Technologies completed )〕 == History == MIPS Computer Systems Inc. was founded in 1984〔CrunchBase.

Other principal founders were Skip Stritter, formerly a Motorola technologist, and John Moussouris, formerly of IBM.〔James DeTar, Investors Business Daily. "(Panel: Information Technology Still Early Stage )." October 6, 2010. Retrieved September 16, 2011.〕 The initial CEO was Vaemond Crane, who left early and was replaced by Bob Miller, a former senior IBM and Data General executive. Miller ran the company through its IPO and subsequent sale to Silicon Graphics. In 1988, MIPS Computer Systems designs were noticed by Silicon Graphics (SGI) and the company adopted the MIPS architecture for its computers.〔Om Malik, Forbes. "(Can MIPS beat ARM? )." December 2, 1998. Retrieved September 19, 2011.〕 A year later, in December 1989, MIPS held its first IPO. That year, Digital Equipment Corporation (DEC) released a Unix workstation based on the MIPS design. After developing the R2000 and R3000 microprocessors, a management change brought along the larger dreams of being a computer vendor. The company found itself unable to compete in the computer market against much larger companies and was struggling to support the costs of developing both the chips and the systems (MIPS Magnum). To secure the supply of future generations of MIPS microprocessors (the 64-bit R4000), SGI acquired the company in 1992〔PC Magazine. "(SGI )."

On June 30, 1998, MIPS held an IPO after raising about $16.3 million with an offering price of $14 a share.〔〔Debora Vrana, Los Angeles Times.
