1. MIPS simulators There are 3 widely used MIPS simulators PC-SPIM, MARS, QTSPIM. PC-SPIM (the one we should use) the oldest one with poor graphics Very simple features and easy to start to work More exact simulation of delayed loads and branches. MARS, QTSPIM The newer simulators with rich graphics Lots of features, helps and complex menus. Not so exact simulation of some hardware features of MIPS.

2. SPIM simulator PC-SPIM Download the latest version of PC-SPIM from http://www.cs.wisc.edu/~larus/SPIM and save it on your machine or find the already downloaded pcspim.zip file locally in the folder: http://ac.aua.am/arm/Public/2016-Spring-Computer- Organization/Software/ http://ac.aua.am/arm/Public/2016-Spring-Computer- Organization/Software/ Unzip the file. Click on the setup.exe program. Most likely all you will do is click buttons to accept the defaults. SPIM by default is installed in C:\Program Files\PCSpim. You’ve finished the installation.
