Design of a lightweight real-time streaming kernel

This report describes a exible real-time kernel, which is optimised for data-streams, to be used for multi-processor environments. Currently, two processors are used: the MSP430 and the ARM 946E-S. For the rst architecture, an in-house kernel has been developed by Tjerk Hofmeijer. For the ARM architecture, the currently available kernel implementations either lack support for dynamic real-time scheduling or are not available. This document describes the kernel BasOS, which was developed within this project. BasOS is a exible real-time kernel with low memory usage, ecient interrupt handling, both real-time and non-real-time scheduling. The kernel has a programmer-friendly interface and supports several peripherals, like the USART (serial port), USB and the Montium processors. Also, several tools, which support the use of BasOS: a stack usage predictor, a loader of dynamic tasks and a second stage boot loader.
