 The '''[[Wikipedia:SGI_O2|O2/O2+]]''' is Silicon Graphics's successor of the [[IP22|Indy]] workstation.  It comes in several versions with [[R5000]], [[RM5271]], [[RM7000]], [[R10000]] or [[R10000|R12000]] processors. The firmware is a 32-bit [[ARC|ARCS]].

-Currently only [[R5000]] based IP32 (O2) systems are well supported in Linux. Framebuffer works, but to get a usable X you need a small patch. Experimental patches for audio exists and did work for a while, until the kernel was made 64-bit only for IP32.

 The '''O2''' Workstation is based around the [[CRIME]], [[MACE]], [[VICE]], and [[GBE]] ASICs. CRIME ASIC is the main system ASIC which interfaces the MIPS cpu, memory system and the I/O system in the MACE ASIC.  CRIME ASIC also contains the 3D gfx rendering engine which renders to main system memory -- part of which is used as the frame buffer which is DMA'ed to a video connector using the GBE ASIC.  A MACE chip is used to provide legacy device support (serial, parallel, video, RTC...). [[VICE]] ASIC is used to process video streams and images stored in memory.
