Classification of interrupts - computer architecture, Computer Engineering

Assignment Help:

Classification of interrupts:

1. a) asynchronous

external components or hardware malfunction

1.b)synchronous

function of program state (for example overflow, page fault)

2a. coerced

from OS or hardware (protection violation ,page fault)

2b. user request

OS call

3a. Non-Maskable

User cannot disable processing

3b. User Maskable

User can disable processing

4a. within an instruction

Usually synchronous - Harder to deal with

4b. between Instructions

Usually asynchronous

5a. Termination

5b. Resume

As if nothing is happened? Program will continue to execution
