Key Points

The aim is to compare the performance of Rate Monotonic Scheduling and Earliest Deadline First algorithms on ARM Cortex-M4 microcontrollers.
Implemented RMS and EDF scheduling in FreeRTOS v10 on ARM Cortex-M4 microcontroller (STM32F407).
Conducted empirical evaluations under realistic periodic workloads with five periodic tasks.
Compared task completion times and system responsiveness.
Rate Monotonic Scheduling showed a higher guaranteed rate of task completion compared to Earliest Deadline First under specific workloads.
EDF performed better in terms of task response time in highly dynamic scenarios.
Empirical results provide practical insights differing from prior simulation-based studies.
