When it comes to operating systems, Linux® is perhaps the world’s most popular open source OS. Linux has been running on thousands of MIPS devices that have shipped in very large volume (north of several billions of units).
The MIPS ISA (MIPS32, MIPS64 and microMIPS) is fully supported in Linux, with Imagination and our licensees providing frequent patches for new architecture implementations and features. A stable branch from Imagination can be found at www.linux-mips.org.
