The chief aim of the EU project entitled "Multi-Core Execution of Hard Real-Time Applications Supporting Analysability" (MERASA) is to make cars and planes more energy-efficient, economical, and safe. On 3 December 2007 a contract was signed at the University of Augsburg between the European Community and the Augsburg computer scientist Professor Dr. Theo Ungerer (Chair of Systems and Networking), who is coordinating the three-year project. It is being financed by a 2.1 million euro subsidy from the EU.
How can cars, planes and machines in general be made safer, more economical and more energy-efficient? For instance, ABS systems in cars could become even safer if the performance of the electronic control unit is increased. Control units with higher performance levels allow to optimize the fuel consumption of engines through improved regulation, to name just one benefit. However, all of these systems need a guarantee that the tasks can be executed within a fixed and very short time interval. Such systems require what are known as "hard real-time constraints". There are currently very few processors that can guarantee the necessary execution deadlines. Despite the high performance levels of today's PC processors, these processors are not suitable for applications in "embedded systems" such as ABS or engine regulation. Moreover, they are too expensive. In turn, the relatively simple processors that are normally installed in "embedded systems" have limited performance capability and are not able to meet the higher standards of safety and cost-effectiveness that the future will bring.
Embedded processors that satisfy hard real-time constraints
The EU project MERASA sets out to develop embedded processors that use multi-core technology to satisfy hard real-time constraints. Multi-core technology is a procedure in which several processors are built into one chip. "To this end, we at the University of Augsburg will develop new real-time-capable processor structures in collaboration with our colleagues at the Barcelona Supercomputing Center. We will implement them prototypically, and at the same time design the corresponding real-time-capable operating system software here in Augsburg," explains Ungerer.
To guarantee real-time capability, software tools that can calculate the worst-case execution time are required. These software tools are to be provided as part of the MERASA project by researchers at Paul Sabatier University in Toulouse and at Rapita Systems Ltd in the UK. Ungerer says: "Hand in hand with the hardware developers in Augsburg and Barcelona, our colleagues in France and England will develop suitable software solutions for the multi-core processors that we as a group are endeavouring to create. We are certain that, at the end of the three-year MERASA project, we will be able to present convincing prototypes of a new multi-core processor, an adequate operating system and software tools that are precisely tailored to the requirements of the program analysis of hard real-time applications."
Manufacturers and users involved from the start
In order to ensure the best possible transfer and user process, partners in industry - both processor manufacturers and users - will be involved right from the start in the development of the hardware and software solutions that the project aims to find. The company Honeywell spol. s.r.o. in Brünn (Czech Republic) will work on the operability of an autonomous control application for cars and for planes based on the MERASA developments. Likewise, the processor manufacturers Infineon (Munich/Bristol) and NXP (Eindhoven), and the application companies Airbus France, European Space Agency and Bauer Maschinen (Schrobenhausen) are integrated into the project through an Industrial Advisory Board, in order to support the hardware and software developments from the beginning and to test them in pilot projects.
"This integration of renowned companies from different European states," adds Ungerer, "also clearly demonstrates that one aim of our MERASA project is to make an important contribution to the future competitiveness of Europe in the key segments of the motor, aerospace and machine construction industries."Contact:

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
