software interrupt         
An interrupt caused by a specific machine language operation code (e.g. the Motorola 68000's TRAP, the {IBM System/390}'s SVC or the ARM's SWI) rather than by a hardware event. As with a hardware interrupt, this causes the processor to store the current state, store identifying information about the particular interrupt, and pass control to a first level interrupt handler. A trap is similar except that it is caused by an unexpected software condition or error (e.g. divide by zero, undefined instruction) rather than a deliberate instruction. (1995-02-14)

¦ verb
1. stop the continuous progress of.
stop (a person who is speaking) by saying or doing something.
2. break the continuity of (a line, surface, or view): a sunken fence which doesn't interrupt the view across the fields.
Derivatives
interruptible adjective
interruptive adjective
Origin
ME: from L. interrupt-, interrumpere 'break, interrupt', from inter- 'between' + rumpere 'to break'.

Interrupt

In digital computers, an interrupt (sometimes referred to as a trap) 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, ISR) to deal with the event. This interruption is often temporary, allowing the software to resume normal activities after the interrupt handler finishes, although the interrupt could instead indicate a fatal error.

Interrupts are commonly used by hardware devices to indicate electronic or physical state changes that require time-sensitive attention. Interrupts are also commonly used to implement computer multitasking, especially in real-time computing. Systems that use interrupts in these ways are said to be interrupt-driven.
