21469  interrupt latency

Question asked by zanzibar on Feb 15, 2011

Hi,

 

I have some real time constraints in my system.

What is the interrupt latency for 21469 ?

I am interested by using VDK for some tasks.What is the penalty to use it in terms of latency ? How many cycles should I loose with my harddware interrupt  ? 

Are there some ways to garantee interrupt latency with VDK or other OS ?

 

Thanks,
