    The Java language provides many benefits to application developers, including memory access safety, platform portability, and very high levels of productivity. However, some of the very Java language features that bring these benefits, such as the garbage collector, have also made it difficult or impossible to create applications with bounded response time characteristics. Implementations of the r... View full abstract»

    The past few years have witnessed the emergence of many real-time networked applications on the Internet. These types of applications require special support from the underlying network such as reliability, timeliness, and guaranteed delivery, as well as different levels of service quality. Unfortunately, this support is not available within the current "best-effort" Internet architecture. In this... View full abstract»

    End-to-end predictability of remote operations is essential for many fixed-priority distributed real-time and embedded (DRE) applications, such as command and control systems, manufacturing process control systems, large-scale distributed interactive simulations, and testbeam data acquisition systems. To enhance predictability, the Real-time CORBA specification defines standard middleware features... View full abstract»

    Power and energy consumption has recently become an important issue and consequently, power-aware techniques are being devised at all levels of system design; from the circuit and device level, to the architectural, compiler, operating system, and networking layers. In this paper, we concentrate on power-aware design techniques for real-time systems. While the main focus is on hard real-time, soft... View full abstract»

    The new millennium heralds the convergence between computing, communication, and the intelligent control of our physical environments. Embedded systems often have a long life cycle. This paper reviews our research group's work on how to upgrade embedded control systems without shutting them down, and how to protect the system from bugs and attacks that could be introduced by software upgrades.

    The architecture of tools for the determination of worst case execution times (WCETs) as well as the precision of the results of WCET analyses strongly depend on the architecture of the employed processor. The cache replacement strategy influences the results of cache behavior prediction; out-of-order execution and control speculation introduce interferences between processor components, e.g., cac...

    Sensor networks can be considered distributed computing platforms with many severe constraints, including limited CPU speed, memory size, power, and bandwidth. Individual nodes in sensor networks are typically unreliable and the network topology dynamically changes, possibly frequently. Sensor networks also differ because of their tight interaction with the physical environment via sensors and act... View full abstract»

    Researchers in the real-time system community have designed and studied many advanced scheduling algorithms. However, most of these algorithms have not been implemented since it is very difficult to support new scheduling algorithms on most operating systems. To address this problem, we enhance the scheduling mechanism in Linux to provide a flexible scheduling framework. In the real-time and embed... View full abstract»

    On 29 December 1926, His Majesty King Alfonso XIII, accompanied by His Royal Highness the Infante Fernando and the President of the Spanish government, General Primo de Rivera, presided at the inaugural formalities of the automatic telephone service in the city of Madrid. The formal ceremony was held at the exchange located in the district of Salamanca. This event was the culmination of a project ... View full abstract»

    Real-time systems are an important class of process control systems that need to respond to events under time constraints, or deadlines. Such systems may also be required to deliver service in spite of hardware or software faults in their components. This fault-tolerant characteristic is especially critical in systems whose failure can cause economic disaster and/or loss of lives. This paper repor... View full abstract»

    Hybrid system theory lies at the intersection of the fields of engineering control theory and computer science verification. It is defined as the modeling, analysis, and control of systems that involve the interaction of both discrete state systems, represented by finite automata, and continuous state dynamics, represented by differential equations. The embedded autopilot of a modern commercial je... View full abstract»
