Fast Interrupt Requests (FIQs) are a specialized type of Interrupt Request, a standard technique used in computer CPUs to deal with events which need to be processed as they occur such as receiving data from a network card, or keyboard or mouse actions. FIQs are specific to the ARM CPU architecture, which supports two types of interrupts; FIQs for fast, low latency interrupt handling and Interrupt Requests (IRQs), for more general interrupts.
