In computing, '''interrupt latency''' refers to the delay between the start of an Interrupt Request (IRQ) and the start of the respective Interrupt Service Routine (ISR).<ref name="Yiu_2016_Latency"/> For many operating systems, devices are serviced as soon as the device's [[interrupt handler]] is executed. Interrupt latency may be affected by [[microprocessor]] design, [[interrupt controller]]s, [[Interrupt#Masking|interrupt masking]], and the [[operating system]]'s (OS) interrupt handling methods.<ref>{{Cite journal|last1=Lin|first1=Feng|last2=Ashley|first2=David T.|last3=Burke|first3=Michael J.|last4=Heymann|first4=Michael|date=1999|title=A Hybrid System Solution of the Interrupt Latency Compatibility Problem|journal=SAE Transactions|volume=108|pages=2112–2125|jstor=44733861|issn=0096-736X}}</ref>
