Thank you for your response! You can find links in the URL of the package to a paper and to my Dissertation. It explains this tool in detail, and also some similar tools (SPIM/QtSPIM too).
Related to SPIM, the version that is in Debian is 8.0 (old, yes). But there is a newer version that uses Qt called QtSPIM, version 9.1.12 uploaded to SourceForge in December 2013. This version is not that old. If you didn't know about it, you can find it here: http://spimsimulator.sourceforge.net/ By the way, in my University I used, as student, MARS ( http://courses.missouristate.edu/kenvollmar/mars/). It's written in Java and I found it easy to use (it has an integrated editor). Now, this package (DrMIPS) isn't competing with SPIM or MARS, though they are used in education. SPIM and MARS support almost all MIPS instructions and pseudo-instructions and also support floating point operations and syscalls. They show, during the simulation, the registers, data memory and assembled code. They are a bit like debuggers (but simulated). DrMIPS supports a small subset of instructions/pseudo-instructions and no floating point operations or syscalls. However, DrMIPS displays a graphical representation of the datapath (and its state), both unicycle and pipeline versions (with and without hazard detection and resolution). You can find screenshots in the URL. And DrMIPS is available for Android too (not in Google Play, though). It's most useful to understand how the MIPS datapath, and also pipelining, work. I would say that, for Operating Systems, SPIM and MARS are more useful (syscalls, large instruction set, etc), unless the course includes Computer Architecture topics where the graphical datapath would be useful. For Computer Architecture, I would say they are both useful. SPIM/MARS for assembly programming and DrMIPS to understand how the datapath works. 2014-06-12 14:41 GMT+01:00 Gunnar Wolf <gw...@gwolf.org>: > Hi Bruno, > > > * Package name : drmips > > Version : 1.2.1 > > Upstream Author : Bruno Nova <brunomb.n...@gmail.com> > > * URL : https://bitbucket.org/brunonova/drmips/ > > * License : GPL > > Programming Lang: Java > > Description : Educational MIPS simulator - DrMIPS > > (...) > > I am the author of the program.
