Mars simulator for mips architecture is a very nice and simple tool with a clean and intuitive gui. In class, you have been learning about the datapath and how a singlecycle cpu works. Historically, most, but not all, python releases have also been gplcompatible.
The mars program is a combined assembly language editor, assembler, simulator, and debugger for the mips processor. Think of the python code as your translation from the requirements. They are all simulations of the simple mips r2000 singlecycle processor. The simulator was written in order to support computer architecture students with a free and crossplatform tool that allows them to run programs written in the mips64 assembly dialect and see how the cpu behaves during the execution, experimenting with various aspects of. The aim is to not only have the entire mips isa implemented and simulated, but to have a mips ide. Compiling python to mips mary fletcher colby college wiki. Spim does not execute binary compiled programs spim implements almost the entire mips32 assemblerextended instruction set. Probably since spim uses the underlying machine architecture simulating the 32 bit mips on a 64 bit architecture would mean lots of changes in the simulator. Spim is a selfcontained simulator that runs mips32 programs. Contribute to fbrossermipssimulator development by creating an account on github.

It can simulate all three fundamental caching schemes. You need to tell it that thats what you want explictly, otherwise it will just keep on executing the next instruction so it will end up in an infinite loop where it executes addmeth and then the print integer syscall over and over the exit syscall in spimmars is number 10, i.

Fully graphical mips simulator, with a simple text editor. This program simulates a processor cache for the mips instruction set architecture. As it stands maybe a loop and adding up the values is next but there is no clear link to your homework assignment or what we call the requirements. At the bottom of the list of files, there is a link to download a gnu tarball, which will get all the files in the latest version of the system. If nothing happens, download the github extension for visual studio and try again. Unlike many available tools for mips processor simulation such as spim 1, visual mips is fully configurable and can be used to.
Learn more installation of mars mips simulator on ubuntu 11. It takes in a text file in hex, and needs to output the register contents and the decoded instruction after every instruction. For detailed directions, refer to the mars tutorial. So i convert the hex file to binary to grab the opcodes, rs, rt, rd, funct, and sham field so i can figure out what instruction it is. Welcome to the home page of edumips64, a free as in free speech visual and crossplatform mips64 cpu simulator.
