What is the difference between FIQ and IRQ interrupt system?

Question

I want to know the difference between FIQ and IRQ interrupt system in any microprocessor, e.g: ARM926EJ.

Answer 1

FIQs are higher priority, no doubt, remaining points i am not sure..... FIQs will support high speed data transfer (or) channel processing, where high speed data processes is required we use FIQs and generally IRQs are used normal interrupt handlling.
