Special session

Beyond cyclictest:
A Unified Benchmark Framework for POSIX Compliant RTOS on ARM processor

Presented byLinaro Limited

While cyclictest focuses on scheduler latency, modern RTOSes require a more holistic view. This talk presents a new, unified benchmark framework for any POSIX-compliant RTOS on ARM. We go beyond cyclictest to measure critical E2E system latencies, including ISR, task preemption, IPC, and multi-core lock contention. By using a high-resolution & low overhead timer and collecting hardware performance counters, our framework provides a complete picture of RTOSes system predictability.
