Real Sáez, Jorge Vicente; Sáez Barona, Sergio; Crespo, Alfons(Association for Computing Machinery, 2018)
[EN] This position paper follows from a previous proposal to integrate a time-triggered scheduler in a prioritybased, preemptive scheduler such as that supported by Ada¿s task dispatching policy FIFO Within Priorities . ...
[EN] Partitioned architectures isolate software components into independent partitions whose execution will not interfere with other partitions, preserving temporal and spatial isolation. Hierarchical scheduling can ...
Sáez Barona, Sergio; Real Sáez, Jorge Vicente; Crespo, Alfons(Springer, 2014)
The real-time attributes of a concurrent task define the parameters that will determine when the task can be allocated the required resources. Typical examples are the task s priority, the deadline, and the CPU (or CPUs) ...
