Interrupt latency in Cortex-A9

Former Member
Former Member over 10 years ago

Hello everybody!

Does anyone know how long a simple interrupt routine takes? I'd like to know more or less the order of magnitude: 100-200 ns, 1 us, 10-20 us, 100-200 us? I searched this information in the Cortex-A9 TRM, but I didn't find anything regarding interrupt timing.

Thanks in advance,

sticken.
