MIPS simulator written in Python. As of writing, this can:
- disassemble machine code provided in hex (good coverage)
- assemble MIPS assembly code (bad coverage)
Create an input file named input.txt and put your program's machine code or assembly code in that file. An example for machine code is like so:
0x8C0A0020
0x02328020
0x2268FFF4
0x016D4022
This corresponds to the following instructions:
lw $t2, 32($0)
add $s0, $s1, $s2
addi $t0, $s3, -12
sub $t0, $t3, $t5Once the input file is set up, run python3 src/main.py [-a] > output.txt in your terminal of choice and the simulation output will show up in output.txt. Include the -a flag only if your input file already contains MIPS assembly code.
After each instruction, the program outputs the entire architectural state.
I should do this in Julia sometime...
I used Digital Design and Computer Architecture extensively as a reference. Thanks, Harris & Harris!
