Interrupt handling - computer architecture, Computer Engineering

Interrupt handling:

Handling Interrupts

 Several  situations where the processor should avoid interrupt requests

  • Interrupt-enable
  • Interrupt-disable

 Typical scenario

  • Processor interrupts the program being executed
  • Device raises interrupt request
  • Processor disables interrupts &acknowledges interrupt
  • Interrupt-service routine executed
  • Interrupts enabled & program execution resumed

A corresponding circuit for an open-drain bus used to implement a general interrupt-request line.
