In a computer, an interrupt request (or IRQ) is a hardware signal sent to the processor that temporarily stops a running program and allows a special program, an interrupt handler, to run instead. Hardware interrupts are used to handle events such as receiving data from a modem or network card, key presses, or mouse movements.
Interrupt lines are often identified by an index with the format of IRQ followed by a number. For example, on the Intel 8259 family of PICs there are eight interrupt inputs commonly referred to as IRQ0 through IRQ7. In x86 based computer systems that use two of these PICs, the combined set of lines are referred to as IRQ0 through IRQ15. Technically these lines are named IR0 through IR7, and the lines on the ISA bus to which they were historically attached are named IRQ0 through IRQ15
Newer x86 systems integrate an Advanced Programmable Interrupt Controller (APIC) that conforms to the Intel APIC Architecture. These APICs support a programming interface for up to 255 physical hardware IRQ lines per APIC, with a typical system implementing support for only around 24 total hardware lines.

An interrupt is an external asynchronous input that informs the microprocessor to complete the instruction that is currently executing and fetch a new routine in order to offer service to the I/O device.
Once the I/O device is serviced, the microprocessor will continue with the execution of its normal program.

• Traps : Sometimes traps are known as software interrupts. traps are raised by user programs, to invoke an OS functionality.
• Exceptions : Exceptions are generated automatically by the processor itself as a result of an illegal instruction.Faults are recoverable errors (such as page fault). Aborts are difficult to recover (such as divide by 0).

08:15 Prgrammable Interrupt Controller (8259): 8259 (Programmable interrupt controller) relays upto 8 interrupt to CPU
• Devices raise interrupts by an ‘interrupt request’ (IRQ)
• CPU acknowledges and queries the 8259 to determine which device interrupted
• Priorities can be assigned to each IRQ line
• 8259s can be cascaded to support more interrupts
11:12 Advanced Programmable Interrupt Controller (APIC): External interrupts are routed from peripherals to CPUs in multi processor systems through APIC
• APIC distributes and prioritizes interrupts to processors
• Interrupts can be configured as edge or level triggered
• Comprises of two components
– Local APIC (LAPIC)
– I/O APIC
• APICs communicate through a special 3-wire APIC bus.

Aooo-ooooh Aooo-ooooh Thought I headed straight Thought I had it waiting for me Thought it was my fate I was only waiting for the sky to fall down The sword of Damocles Or at least I thought it was Had me on my knees That's when I saw it had the shape of a cross Aooo-ooooh I'm ready to give it up (up up up up up up..) Aooo-ooooh I heard the call, but I won't follow 'Cause now I'm breaking up with God I've had it with shame, I've had it with sorrow Now I'm breaking up with God And the devil too Now I wanna dance the night away Aoooo Reach my heaven alive A world that's black and white Has evil haunting every corner Demons in the night And no love, no love for the one who ain't right Aooo-ooooh I heard the call, but I won't follow 'Cause now I'm breaking up with God I've had it with shame, I've had it with sorrow Now I'm breaking up with God And the Devil too Now I wanna dance the night away Aoooo Reach my heaven alive Aaaah aaah aaah Aaaah aaah aaah (We'll lead you home...) Aooo-ooooh I heard the call, but I won't follow 'Cause now I'm breaking up with God I've had it with shame, I've had it with sorrow Now I'm breaking up with God I heard their call, but I won't follow 'Cause now I'm breaking up with God I've had it with shame, I've had it with sorrow Now I'm breaking up with God And the Devil too Now I wanna dance the night away Aoooo Reach my heaven alive Aoooo Now I wanna touch you right away Aoooo, oooh Find my own heaven alive Aooo-ooooh
