Dependability and fault tolerance will play an ever increasing role when using future technology nodes. The paper presents a fault-tolerance strategy for invasive networks on chip (i-NoC). The strategy focuses on permanent faults, resulting from either process fluctuations or aging effects and briefly outlines counter measurements against transient faults. We propose a scalable scheme for detection...
In this paper, we propose an approach for energy-aware FPGA-based query acceleration for databases on embedded devices. After the analysis of an incoming query, a query-specific hardware accelerator is generated on-the-fly and loaded on the FPGA for subsequent query execution using partial dynamic reconfiguration. For each SQL query operation, a pre-synthesized partial bitstream implementation exists...
The automotive community introduced Ethernet as a packet-switched point-to-point network. Possible fields of application are telematics, advanced driving assistance and a backbone. Currently, CAN, FlexRay and MOST are used to interconnect these applications. With Ethernet the bandwidth is rising but the networking requirements are still the same as for existing field buses. Consumer Ethernet does...
As a result of the increased demand for bandwidth, current automotive networks are getting more heterogeneous. New technologies like Ethernet as a packet-switched point-to-point network are introduced. Nevertheless, the requirements on stand-by power consumption and short activation times are still the same as for existing field buses. Ethernet does not provide wakeup mechanisms that are sufficient...
Due to ever-increasing bandwidth requirements of modern automotive applications, Ethernet AVB is becoming a standard high-speed bus in automotive E/E architectures. Since Ethernet AVB is tailored to audio and video entertainment, existing analysis approaches neglect the specific requirements and features of heterogeneous E/E architectures and their applications. This paper presents a timing analysis...
Ethernet is currently being discussed within the automotive community to become a general network technology for interconnecting future distributed automotive systems. If this is the case, a complete tool chain will be necessary to support developers to implement their functions. One important component is the availability of tools to monitor, generate, manipulate, and simulate traffic in distributed...
Today's premium vehicles are equipped with a multitude of Advanced Driver Assistance Systems (ADAS) which present additional driving information or even actively influence the vehicle behavior. These are normally highly distributed real-time systems which process information from distributed sensors like cameras or radar sensors. To fulfiill the high data rates and real-time requirements of these...
