This is a updated version of air_processor2, which features a more realistic and brand new execute function. This CPU also has a built in kernel system, which has airOS loaded on to it. This project runs airOS as a demo project. It also has a helloWorld program loaded onto the OS, so you can execute it to test it. "/help" will give you the entire list of commands to the OS.
