The Interrupt Controller (INTC) provides the ability to prioritize, block, and direct
Interrupt Requests (IRQs). It can fail by dropping or delaying IRQs, directing them to the
wrong core or handler, or by creating spurious IRQs. 

According to this information, what should I do for detect dropping or delaying IRQs?

Hello,

Applications that are not resilient against spurious or missing interrupt requests may need to include detection or protection measures on the system level.
So in other words you will implement SW which will monitor correct behavior of INTC. for example counters for interrupt handlers, etc..

Basically the information is in the standard you want to meet in your project.

Best regards,

Peter
