After a state of art on classical scheduling and on real-ime scheduling, particularly, allowing to define the notions used afterwards and after motivating a new real-time constraint of latency, we propose a model which describes the real-time systems with precedence,periodicity and latency constraints. In this model, the precedences are defined...

First we justify our concern in latency constraints for real-time systems with precedence constraints. We evoke the model based on graph theory used to state and solve the problem of non-preemptive scheduling systems with precedence and latency constraints. Because latency constraints involve pairs of operations related to the graph which...

This paper presents a connection between two real-time models: a deadline-based model and a latency-based model. The importance of the latency-based model is proved through a result showing that two deadlines, instead of a latency constraint, over-constrain the real-time applications. Moreover, we give a deadline-marking algorithm based on the...
