How to get the max interrupt latency in Cortex-R4F

Hi experts,

When I design the real time architecture, I want to get benchmark timing data for interrupt latency to understand the system performance.

So, I ask the chip manufacturer TI. But TI recommend me to post at ARM forum.

I search this question at forum and Technical Reference Manual, but I can not get the answer.

Could you have suggestion?

PS: The interrupt latency I mean is that from interrupt is triggered to the first instruction of the user’s ISR.

Thanks in advanced
