SPIM is a simulated assembly language written for MIPS architecture R2000 and R3000 processors, copyrighted by James R. Larus. This language is often taught in college-level assembly language courses, especially those using the textbook Computer Organization and Design: The Hardware/Software Interface by David A. Patterson, John L. Hennessy, and Nitin Indurkhya (ISBN 1558604286).
SPIM simulators are available for both Windows (PCSpim) and Linux-based (xspim) operating systems.
The name of the language is a reversal of the letters "MIPS".
