. interrupt chaining a) allows cpu to defer processing of low-priority interrupts without masking all interrupts. b) splits interrupt management between first level and second level interrupt handlers. c) is used to handle interrupts but not exceptions. d) is a compromise between the overhead of a huge interrupt table and the inefficiency of dispatching to a single interrupt handler.

Sagot :

The inefficiency of dispatching to a single interrupt handler and the overhead of a large interrupt database are both addressed by interrupt chaining. The right answer is option (d).

The host reads a control register from an I/O device control to obtain input.

How can the CPU manage interrupts?

The majority of current broad sense microchips handle impulses in a similar manner. The CPU switches to a region in memory that either contains the interrupt handling code or an instruction branching to the interrupt handling code when a hardware interrupt occurs, interrupting the execution of the instructions it was currently running.

What interruption is given priority?

With the exception of the divided by zero occurrence, TRAP is the internal interrupt with the greatest priority.
