Interrupt: History & Applications

In digital computers, an interrupt is a request for the processor to interrupt currently executing code (when permitted), so that the event can be processed in a timely manner. If the request is accepted, the processor will suspend its current activities, save its state, and execute a function called an interrupt handler (or an interrupt service routine…

Interrupt relationships Subject–Predicate–Object triples

TTTA extracted 80 structured relationships around Interrupt. Examples in this analysis include Interrupt → causes → may have the same interrupt type and thus the same interrupt handler and Interrupt → is a → request for the processor to interrupt currently executing code. The table shows each extracted connection, where it came from and its confidence.
