Latency Measurements #################### This benchmark measures the latency of selected kernel capabilities, including: * Measure time to switch from ISR back to interrupted thread * Measure time from ISR to executing a different thread (rescheduled) * Measure average time to signal a semaphore then test that semaphore * Measure average time to signal a semaphore then test that semaphore with a context switch * Measure average time to lock a mutex then unlock that mutex * Measure average context switch time between threads using (k_yield) * Measure average context switch time between threads (coop) * Time it takes to suspend a thread * Time it takes to resume a suspended thread * Time it takes to create a new thread (without starting it) * Time it takes to start a newly created thread * Measure average time to alloc memory from heap then free that memory Sample output of the benchmark:: *** Booting Zephyr OS build zephyr-v2.6.0-1119-g378a1e082ac5 *** START - Time Measurement Timing results: Clock frequency: 1000 MHz Average thread context switch using yield : 9060 cycles , 9060 ns Average context switch time between threads (coop) : 9503 cycles , 9503 ns Switch from ISR back to interrupted thread : 14208 cycles , 14208 ns Time from ISR to executing a different thread : 9664 cycles , 9664 ns Time to create a thread (without start) : 3968 cycles , 3968 ns Time to start a thread : 12064 cycles , 12064 ns Time to suspend a thread : 12640 cycles , 12640 ns Time to resume a thread : 12096 cycles , 12096 ns Time to abort a thread (not running) : 2208 cycles , 2208 ns Average semaphore signal time : 8928 cycles , 8928 ns Average semaphore test time : 2048 cycles , 2048 ns Semaphore take time (context switch) : 13472 cycles , 13472 ns Semaphore give time (context switch) : 18400 cycles , 18400 ns Average time to lock a mutex : 3072 cycles , 3072 ns Average time to unlock a mutex : 9251 cycles , 9251 ns Average time for heap malloc : 13056 cycles , 13056 ns Average time for heap free : 7776 cycles , 7776 ns =================================================================== PROJECT EXECUTION SUCCESSFUL
