Real-time systems require the formal guarantee of timing-constraints, not only for the
individual tasks but also for the data-propagation paths. A cause-effect chain describes the …

A cause-effect chain is used to define the logical order of data dependent tasks, which is
independent from the execution order of the jobs of the (periodic/sporadic) tasks. Analyzing …

Real-time systems require a formal guarantee of timing-constraints, not only for individual
tasks but also for data-propagation. The timing behavior of data-propagation paths in a …

Real-time systems require the formal guarantee of timing constraints, not only for the
individual tasks but also for the end-to-end latency of data flows. The data flow among …

A data chain is a sequence of periodic realtime communicating tasks that are processing the
data from sensors up to actuators. It determines an order in which the tasks propagate data …

Many industrial real-time systems rely on the implicit register communication paradigm to
minimize overheads and ease distributed development. Here, tasks follow a simple input …

In many embedded systems, for instance, in the automotive, avionic, or robotics domain,
critical functionalities are implemented via chains of communicating recurrent tasks. To …

Automotive and avionics embedded systems are usually composed of several tasks that are
subject to complex timing constraints. In this context, the LET paradigm was introduced to …

Analysis and optimization of end-to-end latency in cause-effect chains is an important
problem in real-time systems. Under task-level fixed-priority scheduling, the end-to-end …

Logical Execution Time (LET) allows decoupling the schedule of real-time periodic tasks
from their communication, with the advantage of isolating the communication pattern from …
