RISC OS (英语发音:/rɪskˈɛs/)[4] 是给ARM架构的系统设计的一系列基于图形用户界面的电脑操作系统。它的名字来源于它所支持的精简指令集RISC 架构。 这个OS原本是被艾康電腦Acorn Computers)公司开发,用于他们的1987的Archimedes英语Acorn Archimedes个人电脑,该个人电脑使用的是Acorn RISC Machine处理器。它是由命令行界面桌面环境组成的视窗系统

最新的稳定版本运行在 ARMv3/ARMv4 RiscPC[5](或根据仿真通过VirtualAcorn英语VirtualAcornRPCEmu英语RPCEmu),ARMv5的Iyonix[6]和ARMv7的Cortex-A8处理器[7][8] (如使用的BeagleBoard英语BeagleBoardTouch Book英语Touch Book)。在2011年,一个移植的Cortex-A9英语Cortex-A9 PandaBoard英语PandaBoard已宣布[9]树莓派在公众场合露面的开发版本可免费下载的候选发布版已跟进[10][11][12],这版本已免费提供树莓派用户。[13]
