RTOS Benchmark: A Test Suite for Measuring Core Operation Performance of Real-Time Operating Systems

RTOS Benchmark is a test suite specifically designed to measure the core operation performance of Real-Time Operating Systems (RTOS). It quantifies the time and overhead of basic operations such as thread creation/switching, mutex/semaphore, timers, and message queues through a series of benchmark tests. Currently, it mainly supports Zephyr (qemu_x86, frdm_k64f) and FreeRTOS (frdm_k64f), with plans … Read more
