I want to measure the wake up and sleep time latency of both Cortex-A5 and Cortex-M4, but my power scope can only get me 10us for sleep and wake up overhead for Cortex-M4, not to mention Cortex-A5
I want more precise number
sleep overhead : time spending after executing WFI to real deep sleep
wake up overhead : time spending after receiving an interrupt to stable awake
can someone provide me these numbers for both Cortex-M4 and Cortex-A5?
