Introduction

eCos is an open source, royalty-free, real-time operating system intended for embedded applications. The highly configurable nature of eCos allows the operating system to be customised to precise application requirements, delivering the best possible run-time performance and an optimised hardware resource footprint. A thriving net community has grown up around the operating system ensuring on-going technical innovation and wide platform support.
