Historia
The MIPS R4000 series, released in 1991, extended the MIPS instruction set to a full 64-bit architecture and moved the FPU onto the main die to create a single-chip system. The design was so important to SGI, at the time MIPS major customer, that SGI bought the company in 1992. The R4x00 processors have been available and used in different versions. PC (as in R4000PC) denotes primary cache only and SC denotes secondary cache. The MC versions contain special support for cache architectures in multiprocessor systems. R4000 processors where used in many Silicon Graphics computers, e.g. the Indigo workstations and Crimson servers.
