A company which designs, develops, and licenses reduced instruction set computer
and compilers. MIPS Technologies, Inc. is a wholly-owned subsidiary of Silicon Graphics, Inc.
and operates as an independent unit. MIPS is the successor to the processor business of MIPS Computer Systems which was founded in 1984 and merged with Silicon Graphics on 29 June 1992.
MIPS Technologies developed the world's first RISC VLSI
microprocessors (1985) (or was it the ARM
?), the first commercial 64-bit microprocessor (MIPS R4000
, 1992), announced MIPS R4300i - the first 64-bit RISC processor designed for interactive consumer applications (April 1995). They announced the MIPS R10000 - the next generation general-purpose MIPS microprocessor and the most powerful processor in the world (October 1994).
MIPS' semiconductor company partners participate in the design and development of MIPS processors and software and then produce, market, and support the processors. MIPS itself does not fabricate or sell products. MIPS' semiconductor partners are: Integrated Device Technology
, LSI Logic Corporation
, NEC Corporation
, NKK Corporation
, Philips Semiconductors
, Siemens AG
, and Toshiba Corporation
