Overview

COMET is a research project distributed between two Swedish Unversities, namely Linköping and Mälardalen University. Within the project we are developing new techniques for design and development of real-time and embedded systems, as well as new techniques that enhance functionality of databases that work in embedded and real-time environments

Results achieved

Some of the result of the project include:* A case-study performed at Volvo Construction equipement components, investigating the use of real-time database management systems in vehicular control systems.* Multiple implementations of COMET suited for a variety of types of embedded vehicular control systems.* A concept called Database Pointers, which allow tasks to access a read-time database in an efficient and predictable way.*A Concurrency-control algorithm especially suited for database pointers and embedded real-time control applications.* A component-model which allow components to be weaved using the aspect-oriented paradigm.*A Design method (ACCORD) to design real-time systems using aspects and components.* Two licentiate theses. (One at Mälardalen University, and one at Linköping university.)* Development of various tools to support data management in vehicle control-systems. One doctoral thesis october 2005, one doctoral thesis in march 2006.
