Detailed explanation-1: -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-2: -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-3: -It is a LSI chip which manages 8 levels of interrupts i.e. it is used to implement 8 level interrupt systems. It can be cascaded in a master slave configuration to handle up to 64 levels of interrupts. It can identify the interrupting device. More items
