Abstract

Deeply embedded systems are forced to operate under extreme resource constraints in terms of memory, CPU, time, and power consumption. Typical examples are automotive systems. Today's limousines can be considered (large scale) distributed systems on wheels. There are cars in daily operation consisting of over 60 networked processors (i. e. µ-controllers). Reserved estimations say that in the near future every car will be equipped with about 20 networked µ-controllers, on average. The complexity of these "decentralized computer architectures" can be managed no longer by the application alone. Dedicated embedded operating systems are required to ensure manageability, adaptability, portability, and yet efficiency of the software. Resource sparing operation under (hard) real-time constraints must be the maxim. This paper discusses the design and implementation of a portable, universal runtime executive,
