As programmers, we're all used to writing code in a high-level language like Python, Rust, Go, etc. However, ultimately our computer programs have to run on a CPU--a piece of hardware. CPUs are much more primitive. Really, they're often not much more than a glorified calculator with some memory.
In the file metal/metal.py you will find a small simulated CPU.
Your first task is to write some small programs that run on the
CPU. Make sure you're working in your own branch of the Git repo:
bash $ cd compilers_2022_04
bash $ git checkout -b yourname
Go to the metal/metal.py file and follow the instructions
inside. Reminder: If you want me to be able to look at your code and
answer questions, you will need to commit your code to the repo and
push your changes upstream.
bash $ git push -u origin yourname
