Real-Time Operating Systems

State of the art from a research perspective

Jörgen Hansson, LiU
The number of real-time operating systems being developed by companies and researchers has increased significantly over the last couple of years. The development emerges from the need for application-specific operating system, providing the necessary functionality with minimum cost with respect to system resources. This talk will include an overview of research problems, recent research advances, and developed research platforms. Further, we discuss the degree of flexibility in tailoring a real-time operating system for different types of applications.

The Design of Asterix RTOS

Henrik Thane, MDH
This talk describes a new real-time kernel, Asterix, which in a practical manner makes use of many of the recent advances made in the real-time systems research community. The basic ambition behind the development of the Asterix real-time kernel was to pack state-of the art research results into package such that it can be easily used and understood by people in the embedded systems industry. From an academic point of view the Asterix real-time kernel fulfills all the basic requirements necessary for facilitating different types of timing analyses. For a software designer this signifies that the Asterix real-time kernel has the means to satisfy engineering of real-time software in the same fashion as civil engineers make use of structural calculus when designing bridges or houses.

RTOS of the Next Generation

Jan Lindblad, ENEA
This talk reports on current industrial practice when developing real-time applications on top of real-time operating systems. We discuss the requirements that need to be satisfied by the operating system, and the technical challenges that the real-time designer is faced with when developing software for a real-time operating systems. In doing so, we outline some requirements and technical challenges that we believe need to be handled by the next generation of real-time operating systems.
