mips-simulator

A minimal implementation of a Multi-cycle MIPS Simulator. It is not intended to be used for production use.

It accepts a pseudo-object file, which is a file consisting of multiple 32-bit words, separated by a newline. The program assumes the file is valid. Any line starting with # are treated as comments, and are ignored.

Building The Simulator

Run make clean; make all

Important

It has been tested only on Linux.

Running The Simulator

Run ./mips_simulator pseudo-object-file stats-file. For example: ./mips_simulator tests/1_math_test.o ./math_test.stats
