What is an interrupt lattency?..

Answer / rithi

In real-time 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's interrupt handler is executed. Interrupt
latency may be affected by interrupt controllers, interrupt
masking, and the operating system's (OS) interrupt handling
