Most innovations in the automotive domain are realized by electronics and software. Modern cars have up to 100 Electronic Control Units (ECUs) that implement a variety of control applications in a distributed fashion. The tasks are mapped onto different ECUs, communicating via a heterogeneous network, comprising communication buses like CAN, FlexRay, and Ethernet. For electric vehicles, software functions...
Engine control systems, consisted of ECU hardware, software, sensors, and actuators, are the most significant part of automotive control, and can be considered as mixed-signal systems which interact with engine through sensors and actuators. In this article, we present a component-based modeling and simulation framework for automotive system design. This component framework is compatible with AUTOSAR...
Currently employed manufacturing systems are very often historically grown systems that can comprise several different technologies of control software. Linking these diverse control subsystems in the manufacturing domain is therefore of vital importance to ensure the system's functionality. In this paper we introduce an agent-based approach with agents that integrate a high level control layer and...
The purpose of TAFT fault tolerance studies conducted at CNES is to prepare the space community for the significant evolution linked to the usage of COTS components for developing spacecraft supercomputers. CNES has patented the DMT and DT2 fault-tolerant architectures with 'light' features. The development of a DMT/DT2 testbench based on a PowerPC7448 microprocessor from e2v is presented in this...
Over the past 20 years, a lot of effort has gone into making the vision of ubiquitous computing a reality. A major focus of this effort has been on the understanding of human activity as input to enable the design and implementation of context-aware applications. Context-awareness is a vital enabling technology for ubiquitous virtual reality applications. However, it is only recently that we have...
Multi-core SoC created great opportunities to increase overall system performance while keeping the power in check but also created many design challenges that designers must now overcome. The challenge of doubling performance every two years used to drive superscalar design with more functional units running concurrently or deeper pipeline racing for highest frequency at the cost of higher power...
