PicOS: A Tiny Operating System for Extremely Small Embedded Platforms.

Abstract

We present a certain programming paradigm for implementing low-footprint applications on small embedded platforms and a tiny operating system based on that paradigm. The primary objective of our work was to create a friendly environment for rapid, reliable, and efficient deployment of customizable microcontroller applications primarily (but not necessarily) aimed at the wireless world. The proposed solution, while being characterized by very small resource requirements, offers an interesting flavor of multithreading and provides for well-structured self-documenting layout of the application code.
