Bus-contention aware WCRT analysis for the 3-phase task model considering a work-conserving bus arbitration scheme

Jatin Arora et al.

Summary: The usage of multicore processors in most modern systems is common; however, their application in systems with strict timing requirements remains a subject of ongoing research. The 3-phase task execution model is a helpful tool in controlling the contention in multicore systems due to shared resources like caches and memory buses. By dividing task execution into distinct memory and execution phases, this model improves predictability and enables precise computation of bus and memory contention, leading to improved taskset schedulability.
