EVMK2H: How to measure interupt latency on DSP/ARM

Hi,

We have interrupt latency number reported in the SYSBIOS. See bios_6_76_03_01\packages\ti\sysbios\benchmarks\doc-files. There is no specific measurement on K2H ARM and DSP. But there are C6670 for C66x and evmDRA7XX for A15 numbers for you to refer to.

The code used for SYSBIOS measurement is not published. Let me know what's your goal here?

Regards, Eric

Hi Eric,

Thanks for your info, I get the number from the document.

I want to do further experiment on the interupt latency, so may I know for the example from Processor SDK, how does it work? And do you have the version for EVMK2H (DSP and ARM)?

Thanks.

Hi Eric,

I already try the example and can get some measurements. These result are valuable to us.

So for the interrupt latency (which is not coverd in provided example), is the best way to use GPIO to trigger the signal and use the oscilloscope to measure? 

Thanks.

Thanks Eric.
