Vybrid VF6xx Cortex-A5 and Cortex-M4 wake up and sleep overhead

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?

 

Thanks,
