MIPS-X is a reduced instruction set computer (RISC) microprocessor and instruction set architecture (ISA) developed as a follow-on project to the MIPS project at Stanford University by the same team that developed MIPS.
Unlike its older cousin, MIPS-X was never commercialized as a workstation central processing unit (CPU), and has mainly been seen in embedded system designs based on chips designed by Integrated Information Technology (IIT) for use in digital video applications.
The PSW register contains some flags that enable interruptions, overflow exceptions and other status information.
[2] The MIPS-X 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 the GNU Compiler Collection (GCC).
Devices such as the ESS VideoDrive system on a chip (SoC) also include a digital signal processor (DSP) (coprocessor) for decoding MPEG audio and video streams.
