'''SPIM''' is a [[MIPS architecture|MIPS]] processor simulator, designed to run [[assembly language]] code for this architecture. The program simulates [[R2000 (microprocessor)|R2000]] and [[R3000]] processors, and was written by [[James Larus|James R. Larus]] while a professor at the [[University of Wisconsin–Madison]].<ref>{{cite web|url=http://pages.cs.wisc.edu/~larus/spim.html|title=SPIM MIPS Simulator|publisher=|accessdate=1 October 2016}}</ref> The MIPS machine language is often taught in college-level assembly courses, especially those using the textbook ''Computer Organization and Design: The Hardware/Software Interface'' by [[David A. Patterson (scientist)|David A. Patterson]] and [[John L. Hennessy]] ({{ISBN|1-55860-428-6}}).

The name of the simulator is a reversal of the letters "MIPS".

SPIM simulators are available for Windows (PCSpim), Mac OS X and Unix/[[Linux]]-based (xspim) operating systems. As of release 8.0 in January 2010, the simulator is licensed under the standard [[BSD license]].

In January, 2011, a major release version 9.0 features QtSpim that has a new user interface built on the [[cross-platform]] [[Qt (toolkit)|Qt UI framework]] and runs on [[Windows]], [[Linux]], and [[macOS]]. From this version, the project has also been moved to [[SourceForge]] for better maintenance. Precompiled versions of QtSpim for Linux (32-bit), Windows, and Mac OS X, as well as PCSpim for Windows are provided.
