Analyzing Data Cache Related Preemption Delay With Multiple Preemptions

Reducing the fault vulnerability of hard real-time systems

“…Indeed, classifying CBs stored in data caches as CBs that can be hit later in the task execution requires a different kind of static analysis. For example, the authors of [17] propose a method to compute the useful data cache blocks of a task. Also, data caches bring in additional issues, like the choice of the write policy (writethrough vs. write-back) and its impact on timing and vulnerability.…”
