I really enjoyed the Nand 2 Tetris course: https://www.nand2tetris.org/
It's a free (well the first half that I did is free) course that really helps you understand computer architecture at a fundamental level. It starts you at basic logic and you build your way up from there. The full course takes you all the way through building a Tetris emulator. It is a very well done course and I highly recommend it.
I wanted to share my work from Project 6 - building an Assembler. I chose to write it in the language I'm most familiar with, python. It translates programs written in the Hack assembly language into binary Hack code.
Call the main function and provide a path to a .asm file, like so:
python3 assembler/main.py add/Add.asmThis will create a file with .hack extension alongside the .asm file.
Optionally, you can provide the debug flag (as either --debug or --d) to see the timing of each step:
python3 assembler/main.py add/Add.asm --debugAnd in addition to producing the output file, it will print something like:
Converting add/Add.asm
Parsed file in 0.00018 secs
First pass in 0.00004 secs
Second pass in 0.00009 secs
Wrote add/Add.hack
Ran in 0.00065 secs
There are no 3rd party libraries involved in this project - everything is in the python standard library!
add unit tests?
