The aim of the 7th IEEE International Symposium on Industrial Embedded Systems (SIES 2012) is to bring together researchers and practitioners from the industry and academia, and provide a platform to report recent developments, deployments, technology trends and research results related to embedded systems and their applications in various industrial environments. SIES 2012 will feature two keynotes...
Summary form only given, as follows. Automation is just one application field of embedded systems, but surely one of the most heterogeneous ones. Automation systems can be found in very different places like traffic control, home and building automation, but also in industrial scenarios like production of cars or petrochemical plants. The first part of the keynote will take the audience on a journey...
Summary form only given, as follows. As technology scales to 22nm and beyond, reliability becomes a serious concern of densely integrated on-chip systems. Aging effects like electro-migration, NBTI (Negative Bias Temperature Instability), TDDB (Time Dependent Dielectric Breakdown) and other effects alter the electric characteristics of circuits and lead finally to transient and/or permanent faults...
Ethernet is increasingly recognized as the future communication standard for distributed embedded systems in multiple domains such as industrial automation, automotive and avionics. A main motivation for this is cost and available data rate. A critical issue in the adoption of Ethernet in these domains is the timing of frame transfers, as many relevant applications require a guaranteed low-latency...
A heterogeneous network, where a switched Ethernet backbone interconnects several existing CAN buses via bridges, is a promising candidate to build a large scale network. For real-time applications, deterministic communication is a key issue. A worst-case delay analysis on such a network has to deal with heterogeneity properties, such as different bandwidths, scheduling policies and bridging strategies...
Driven by the increasing demand for high speed communication of the in-vehicle automotive systems, car manufacturers and suppliers have developed the FlexRay communication protocol. Being dedicated to safety and time-critical applications, the availability of appropriate timing analysis methods for the prediction of the FlexRay timing behaviour is essential. Consequently, several analysis solutions...
In modern embedded platforms, safety-critical functionalities that must be certified correct to very high levels of assurance may co-exist with less critical software that are not subject to certification requirements. Upon such platforms one seeks to satisfy two, sometimes contradictory, goals: (i) being able to certify the safety-critical functionalities under very conservative assumptions, and...
Hierarchical scheduling frameworks (HSFs) provide means for composing complex real-time systems from well-defined independently developed and analyzed subsystems. To support shared logical resources requiring mutual exclusive access in two-level HSFs, overrun without payback has been proposed as a mechanism to prevent budget depletion during resource access arbitrated by the stack resource policy...
A large part of power dissipation in a system is generated by I/O devices. Increasingly these devices provide power saving mechanisms, inter alia to enhance battery life. While I/O device scheduling has been studied in the past for real-time systems, the use of energy resources by these scheduling algorithms may be improved. These approaches are crafted considering a very large overhead of device...
In embedded systems, the timing behaviour of the control mechanisms are sometimes of critical importance for the operational safety. These high criticality systems require strict compliance with the offline predicted task execution time. The execution of a task when subject to preemption may vary significantly in comparison to its non-preemptive execution. Hence, when preemptive scheduling is required...
Audio-Video-Bridging (AVB) is a promising new commercially available Ethernet-based standard providing mechanism for audio and video transmission over Ethernet supporting demanding audio and video transmission delay requirements. This paper addresses the applicability of using AVB in a fully-switched Ethernet network that covers safety-related functions in the aeronautics. Avionic systems leveraging...
Hierarchical scheduling is instrumental to efficiently deploy component-based designs and achieve composability. It allows partitioning resources into multiple levels, hiding the complexity within each partition behind its respective interface. In this paper we focus on the network resource, particularly on Ethernet using ordinary COTS switches, and we show how hierarchical scheduling can be efficiently...
The goal of this paper is to consider a co-design approach between the controller of a process control application and the frame scheduling of a Local Area Network (LAN). More precisely we present a bi-directional relation between the Quality of Control (QoC) provided by the controller and the Quality of Service (QoS) provided by the LAN (relation noted QoS⇋QoC). We present, first, the implementation...
FlexRay, developed by a consortium of over hundred automotive companies, is a real-time communication protocol for automotive networks. A communication cycle in FlexRay consists of an event-triggered component known as the dynamic (DYN) segment, apart from a time-triggered segment. Predicting the worst-case response time of messages transmitted on the DYN segment is a difficult problem. This is because...
Patient monitoring systems are becoming increasingly important in accurately diagnosing and treating growing worldwide chronic conditions especially the obesity epidemic. The ubiquitous nature of wearable sensors, such as the readily available embedded accelerometers in smart phones, provides physicians with an opportunity to remotely monitor their patient's daily activity. There have been several...
Most current-generation Wireless Sensor Network (WSN) nodes are equipped with multiple sensors of various types, and therefore support for multi-tasking and multiple concurrent applications is becoming increasingly common. This trend has been fostering the design of WSNs allowing several concurrent users to deploy applications with dissimilar requirements. In this paper, we extend the advantages of...
