== History ==

=== First hardware ===

In 1981, [[John L. Hennessy]] began the [[Stanford MIPS|MIPS]] (''Microprocessor without Interlocked Pipeline Stages'') project at [[Stanford University]] to investigate [[RISC]] technology. The results of his research convinced him of the future commercial potential of the technology, and in 1984, he took a sabbatical to found [[MIPS Computer Systems]]. The company designed a new architecture that was also called [[MIPS architecture|MIPS]], and introduced the first MIPS implementation, the '''[[R2000 (microprocessor)|R2000]]''', in 1985. The R2000 was improved, and the design was introduced as the '''[[R3000]]''' in 1988. These 32-bit CPUs formed the basis of their company through the 1980s, used primarily in [[Silicon Graphics|SGI]]'s series of [[workstation]]s and later [[Digital Equipment Corporation]] DECstation workstations and servers. The SGI commercial designs deviated from Stanford MIPS by implementing most of the interlocks in hardware, supplying full multiply and divide instructions (among others). The designs were guided, in part, by software architect [[Earl Killian (engineer)|Earl Killian]] who designed the MIPS III 64-bit instruction-set extension, and led the work on the R4000 microarchitecture.<ref name=twsNovZ23>{{cite news

|quote= Earl Killian's early work w... As MIPS's Director of Architecture, he designed the MIPS III 64-bit instruction-set extension, and led the work on the R4000 microarchitecture. He was a cofounder of QED, which created the R4600 and R5000 MIPS processors. Most recently he was chief architect at Tensilica working on configurable/extensible processors.

=== Loongson ===

{{Main article|Loongson}}

[[Loongson]] is a family of MIPS-compatible microprocessors designed by the [[Chinese Academy of Sciences]]' Institute of Computing Technology (ICT). Independently designed by the Chinese, early models lacked support for four instructions that had been patented by MIPS Technologies.<ref>[http://www.mdronline.com/mpr/h/2006/0626/202602.html China's Microprocessor Dilemma]</ref> In June 2009, ICT licensed the MIPS32 and MIPS64 architectures from MIPS Technologies.<ref>[http://www.mips.com/news-events/newsroom/release-archive-2009/6_15_09.dot China’s Institute of Computing Technology Licenses Industry-Standard MIPS Architectures]</ref> Starting in 2006, a number of companies released Loongson-based computers, including [[nettop]]s and [[netbook]]s designed for low-power use.<ref>{{cite web|url=http://www.linuxfordevices.com/c/a/News/Chinese-150-Linux-miniPC-races-OLPC-to-market/ |title=LinuxDevices article about the Municator |archiveurl=https://archive.is/20121216080125/http://www.linuxfordevices.com/c/a/News/Chinese-150-Linux-miniPC-races-OLPC-to-market/ |archivedate=2012-12-16 |url-status=dead }}</ref><ref>{{cite web|url=http://www.linuxdevices.com/news/NS2928309621.html |title=''Yeelong'' Specs |publisher=LinuxDevices |date=22 October 2008 |archiveurl=https://archive.is/20121210034609/http://www.linuxfordevices.com/c/a/News/Netbook-runs-Debian-on-Chinamade-CPU/ |archivedate=10 December 2012 |url-status=dead }}</ref>

==== Dawning 6000 ====

{{Main article|Dawning Information Industry#Dawning 6000}}

The Dawning 6000 [[supercomputer]], which has a projected performance of over 1&nbsp;[[PFLOPS]], will use the [[Loongson]] processor. The Dawning 6000 is currently being jointly developed by the ICT and Dawning Information Industry Company. Li Guojie, chairman of Dawning Information Industry Company and director and academician of the ICT, said research and development of the Dawning 6000 is expected to be completed in two years. By then, Chinese-made high-performance computers will be expected to achieve two major breakthroughs: first, the adoption of domestically made processors; second, the existing cluster-based system structure of high-performance computers will be changed once performance reaches 1&nbsp;PFLOPS.
