This OS is designed from scratch to optimize for speed and code size, targeting the features necessary for a graphing calculator application.

This project is paired with the [interpreter project](https://code.bitgloo.com/clyne/interpreter) (licensed under the GPL), a simple low-memory scripting language. Apart from other core functions, the operating system's goal is to expose calls to the interpreter, and then load the ```init``` script from the calculator.
