Abstract

Embedded systems are a fast growing and exciting market. A real-timeoperating systems is often a necessity in such systems. Most of todays real-time operating systems, both educational and industrial, supports state-of-practice methods for scheduling, analyzing and developing. Many off-the-shelf real-time operating systems lack desirable state-of-the-art features and tools for analyzes and development. The Asterix Framework project aims to fill that gap. This document presents an implementation of a real-time kernel that support state-of-the-art methods. The kernel supports algorithms such as Fixed Priority Scheduling, Immediate Inheritance Protocol, monitoring of both applications and the kernel, interprocess communication by Wait- and Lock-Free channels. The collaboration with Obelix Configuration Tool lead to that memory allocation, initializing of memory areas, etc. can be done off-line and the implementation can be kept simple and hence decrease the size of the kernel. The source code is released as Open Source to make it available for researchers, students and developers in the industry to test new ideas.
