Interrupt — This article is about computer interrupts. For the study of the effect of disruptions on job performance, see Interruption science. In computing, an interrupt is an asynchronous signal indicating the need for attention or a synchronous event in… … Wikipedia
Interrupt storm — In operating systems, an interrupt storm is an event during which a processor receives an inordinate number of interrupts that consume the majority of the processor s time. Interrupt storms are typically caused by hardware devices that do not… … Wikipedia
Interrupt latency — In Realtime Operating Systems, Interrupt latency is the time between the generation of an interrupt by a device and the servicing of the device which generated the interrupt. For many operating systems, devices are serviced as soon as the device… … Wikipedia

Interrupt handler — An interrupt handler, also known as an interrupt service routine (ISR), is a callback subroutine in an operating system or device driver whose execution is triggered by the reception of an interrupt. Interrupt handlers have a multitude of… … Wikipedia
Device driver synthesis and verification — The device driver is a program which allows the software or higher level computer programs to interact with a hardware device. These software components act as a link between the devices and the operating systems, communicating with each of these … Wikipedia
Interrupt request — IRQ redirects here. For the country with the ISO 3166 1 country code, see Iraq. The computing phrase interrupt request (or IRQ) is used to refer to either the act of interrupting the bus lines used to signal an interrupt, or the interrupt input… … Wikipedia
Interrupt priority level — The interrupt priority level (IPL) is a part of the current system interrupt state, which indicates the interrupt requests that will currently be accepted. The IPL may be indicated in hardware by the registers in a Programmable Interrupt… … Wikipedia
interrupt — A signal to the processor generated by a device under its control, such as the system clock, that interrupts normal processing. An interrupt indicates that an event requiring the processor s attention has occurred, causing the processor to… … Dictionary of networking
interrupt request — Abbreviated IRQ. Hardware lines that carry a signal from a device to the processor. A hardware interrupt signals that an event has taken place that requires the processor s attention. The interrupt may come from the keyboard, the network… … Dictionary of networking
Advanced Programmable Interrupt Controller — In computing, an Advanced Programmable Interrupt Controller (APIC) is a more complex Programmable Interrupt Controller (PIC) than Intel s original types such as the 8259A. APIC devices permit more complex priority models, and Advanced IRQ… … Wikipedia
