Multicore processor are well established in classical and tablet personal computers for some year. Such processors use more then one central core for computation and allow to integrate more computational power with smaller costs. However more than 90% of all processors worldwide are not placed in classical IT but are empedded in bigger systems like in modern vehicles or airplanes. Such systems face a very high demand in terms of safety, security an reliability which hinders the use of multicores in such systems. The funded project ARAMiS faces these demands and has the goal to enable the usability of multicore systems in the domains automotive and avionics, as well as later also railway. ARAMiS is the basis for higher traffic safety, traffic efficiency and comfort. In order to achieve this goal the project comprises all necessary competences from more than 30 partners: OEMs from automotive and avionics, Tier1 suppliers, hard and software manufactures and leading research institutions of the corresponding field. The technical goals of ARAMiS comprise hard- and software architectures as well as methodologies, enabling the development of multicore systems for the corresponding domains. Embedded multicore systems will be developed starting from future scenarios and requirements in automotive and avionics. The biggest challenges are the high requirements in safety, reliability, security, and certification. The project is not focused on specific solutions. It focuses on general solutions which can be used in all fields of the targeted domains. Our goal is to demonstrate the usability of multicores in safety critical applications and domains. ARAMiS has a budget of more than 36 million EUR for three years. It is financially supported by the German ministry of science and education. The project recently started in December 2011. This contribution focuses on the presentation of the vision, goals and the content of the project.

As a result of recommendation from the Augustine Panel, the direction for Human Space Flight has been altered from the original plan referred to as Constellation. NASA's Human Exploration Framework Team (HEFT) proposes the use of a Shuttle Derived Heavy Lift Launch Vehicle (SDLV) and an Orion derived spacecraft (salvaged from Constellation) to support a new flexible direction for space exploration. The SDLV must be developed within an environment of a constrained budget and a preferred fast development schedule. Thus, it has been proposed to utilize existing assets from the Shuttle Program to speed development at a lower cost. These existing assets should not only include structures such as external tanks or solid rockets, but also the Flight Software which has traditionally been a ?long pole? in new development efforts. The avionics and software for the Space Shuttle was primarily developed in the 70's and considered state of the art for that time.

The present work aims at the reduction of transmission delay at the level of AFDX ES (Avionics Full Duplex Switched Ethernet End-Systems). To this end, two approaches, namely Network Calculus and response time analysis (RTA), are employed in the computation of upper bound delay. To evaluate the delay regarding different scheduling policies, the arrival curve of the flow on output of ES is established for given traffic shaping algorithm and service mode. Computational analysis shows that Bandwidth Allocation Gap (BAG) based scheduling is the optimal policy at the level of AFDX ES, which leads to the tightest output arrival curve among all possible scheduling policies. BAG-based scheduling consists in assigning higher priority to virtual links with smaller BAG thus corresponding to the well known Rate-Monotonic Algorithm. Furthermore, schedulability criterion are established based on RTA.

A significant step is achieved on the flight control actuation system toward the more electrical aircraft through the Airbus A380, A400M and the A350 development phase ongoing. The A380/A400M/A350 features a mixed flight control actuation power source distribution, associating electrically powered actuators with conventional FlyByWire hydraulic servocontrols. In the scope of the preparation of the future Airbus Aircraft, this paper presents the perspectives of the use of the EMA technologies for the flight control systems in the more electrical aircraft highlighting the main technical challenges need to treat: jamming susceptibility, ?on board? maintenance reduction, Operational reliability increase, power electronics and power management optimization, and regarding the environmental constraints, the predicted performances; the benefits associated to the optimized utilization of on-board power sources.

All Semi Vendors do have multi core CPUs in their portfolio and adding new devices every day. This is the only possibility to grow performance and fulfill Moore's law. Multi core offers a wide variety of possibilities to reduce hardware complexity, reduce power consumption, shrink board space, expand functionality and performance. On the other hand the software complexity goes up and this directly affects the ability to achieve a certified system. The main trend as of today and in the future is the rising number of cores in a single chip and the increasing functionality of the software. As this trend does not stop at safety critical systems, the System/Solution Architects have to question themselves how to guarantee data integrity, robustness, robust portioning, avoid multi point of failures and race conditions. This presentation will highlight ideas, do's and don'ts for those who will design a safety critical multi Core system today or in the near future.
