Interrupt collector

RCReddy

Hi All,

I am using Arm Cortex-A53 based board.I modified a driver module and the interrupt processing.

I have a fundamental question:

Since Arm Cortex-A53 can handle 16 primary interrupts, what happens if all the interrupts arrive at same time. Though ISR's are typically fast, there should be some buffering before interrupt is handled by CPU.

How much is the depth of such quick buffering of such buffer.

If possible, please point to the info [if available online].

Thanks
