How does it take to handle an hardware interrupt? Has anybody measured this?
I need this for buffer size calculation.Forum Discussion

Altera_ForumI imagine that this would depend on what you're doing in the interrupt handler, and especially whether you're doing all the work there or deferring some of it to a tasklet or work queue.

I would do the work in a tasklet. The ISR has only to read a value from the device and to set a flag. Can his be done in less than a ms?
