 Unlike its older cousin, MIPS-X was never commercialized as a workstation CPU, and has mainly been seen in embedded designs based on chips designed by Integrated Information Technology for use in digital video applications.MIPS-X, while designed by the same team and architecturally very similar, is not instruction-set compatible with the mainline MIPS R-series processors.The processor is obscure enough that (as of November 20, 2005) support for it is provided only by specialist developers (such as Green Hills Software), and is notably missing from GCC.
