Sunway (processor): Difference between revisions

'''Sunway''', or '''ShenWei''', ([[Chinese language|Chinese]]:{{lang|zh|神威}}), is a series of computer [[microprocessor]]s, developed by [[Jiāngnán Computing Lab]] ({{lang|zh|江南计算技术研究所}}) in [[Wuxi]], [[China]]. DetailsIt ofuses thea [[reduced instruction set computing]] (RISC) architecture, but details are still sparse.

== History of Sunway processors ==

The Sunway series of microprocessors waswere developed primarilymainy for the use of the military of the [[People's Republic of [[China]]. It is expressed on online forums that the original [[microarchitecture]]<!--the word used, but do not understand rest that is in Chinese--> is believed to be inspired by the [[DEC Alpha]].<ref name="gen123">{{cite web |url=http://bbs.lemote.com/archiver/?tid-22869-page-1.html |title=Jiangnan Computing Lab's Civilian CPU Debut - SW-1 |accessdate=2011-10-31 |author=hswz |date=2009-05-04 |work=bbs.lemote.com }}</ref><ref name="linkedin-chengang">{{cite web|title=LinkedIn profile: Chen Gang|url=https://www.linkedin.com/in/chen-gang-89617986|website=LinkedIn}}</ref> The SW-3 inis particular isthought feltespecially to be based on the [[Alpha 21164]].<ref>{{cite web|url=http://laotsao.wordpress.com/2011/10/29/sw1600-and-alpha-21164/ |title=SW1600 and Alpha 21164|accessdate=2011-10-29 |author=Hung-Sheng Tsao |date=2011-10-29 |work=LaoTsao's Weblog }}</ref>
