Detailed explanation-1: -There are two types of interrupt controller available for the ARM processor: the standard interrupt controller and the vector interrupt controller (VIC).
Detailed explanation-2: -An interrupt is the automatic transfer of software execution in response to a hardware event that is asynchronous with the current software execution. This hardware event is called a trigger.
Detailed explanation-3: -An interrupt first goes to hardware known as Interrupt Controller. This controller will generate an interrupt to the CPU. The process that runs when an interrupt is generated is Interrupt Handler. Interrupt Handler is of two types namely-First Level Interrupt Handler(FLIH) and Second Level Interrupt Handler(SLIH).
Detailed explanation-4: -In computing, a programmable interrupt controller (PIC) is an integrated circuit that helps a microprocessor (or CPU) handle interrupt requests (IRQ) coming from multiple different sources (like external I/O devices) which may occur simultaneously.
Detailed explanation-5: -The Interrupt Controller is a single functional unit that is located in a Cortex-A5 MPCore processor. There is one processor interface per core in the processor. The Interrupt Controller is used to collate and arbitrate between a number of different interrupt sources in the system.
