This paperpresents a LazyDVS scheduling algorithm that offers higher acceptance ratio (number of tasks able to meet their deadline is to number of tasks appearing) with equivalent orlesser energy consumption for battery powered dynamic real time system. ...

In this paper we present a compositional model for distributed virtualized systems communicating over on-chip/off-chip deterministic networks implementing an end-to-end or partial time-triggered paradigm. We derive system-level constraints for combined ...

Network-on-Chip (NoC) is the interconnect of choice for many-core processors and system-on-chips in general. Most of the existing NoC designs focus on the performance with respect to average throughput, which makes them less applicable for real-time ...

This paper applies several variants of application independent time-division multiplexing to MPI primitives and investigates their applicability for different scopes of communication. Thereby, the scopes are characterized by the size of the network-on-...

In this paper we are interested in mixed-criticality applications, which have functions with different timing requirements, i.e., hard real-time (HRT), soft real-time (SRT) and functions that are not time-critical (NC). The applications are implemented ...

The AFDX (Avionics Full DupleX Switched Ethernet) is the backbone network of most recent avionic communication systems. These systems require deterministic buffer dimensioning for certification reasons. As in such systems, static design is often ...

In this paper we are interested in safety-critical real-time applications implemented on distributed architectures using the Time-Sensitive Networking (TSN) standard. The ongoing standardization of TSN is an IEEE effort to bring deterministic real-time ...

Software-defined networking proposes a new paradigm to operate computer networks. Where routers and switches execute predetermined distributed protocols, OpenFlow offers to replace them with devices where the logic that determines the flows of packets ...

Time-triggered networks are widely used for safety-critical applications. Being offline scheduled, flexibility and adaptivity typically come at the price of very low resource utilization, if possible at all. In this paper, we present the Stacked ...

The logical execution time (LET) model increases the compositionality of real-time task sets. Removal or addition of tasks does not influence the communication behavior of other tasks. In this work, we extend a multicore operating system running on a ...

In this paper, we explore a new approach for the security of flow transmission in a Network-on-Chip. This approach is based on a dual mixed criticality approach where the criticality of a flow (HI or LO) is associated to timeliness and security ...
