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
Latency (engineering) — Latency is a measure of time delay experienced in a system, the precise definition of which depends on the system and the time being measured. Latencies may have different meaning in different contexts. Contents 1 Communication latency 1.1 Packet … Wikipedia
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 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
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 vector — An interrupt vector is the memory address of an interrupt handler, or an index into an array called an interrupt vector table or dispatch table . Interrupt vector tables contain the memory addresses of interrupt handlers. When an interrupt is… … Wikipedia
Programmable Interrupt Controller — A Programmable Interrupt Controller (PIC) is a device which allows priority levels to be assigned to its interrupt outputs. When the device has multiple interrupt outputs to assert, it will assert them in the order of their relative priority.… … Wikipedia
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
Non-maskable interrupt — A non maskable interrupt (NMI) is a computer processor interrupt that cannot be ignored by standard interrupt masking techniques in the system. It is typically used to signal attention for non recoverable hardware errors. (Some NMIs may be masked … Wikipedia
CAS Latency Time — Dieser Artikel beschreibt den DRAM Chip. Für das mit diesen Chips aufgebaute DRAM Modul (ugs.: Speicherriegel), siehe Artikel Speichermodul. Dynamic Random Access Memory (DRAM), oder der halb eingedeutschte Begriff Dynamisches RAM, bezeichnet… … Deutsch Wikipedia
