What are the different types of interrupt exceptions?

Types of Interrupts Processor-detected exceptions: Faults — correctable; offending instruction is retried. Traps — often for debugging; instruction is not retried. Aborts — major error (hardware failure)

What are the different types of interrupts?

TYPES OF INTERRUPTS Maskable Interrupt: The hardware interrupts which can be delayed when a much highest priority interrupt has occurred to the processor. Non Maskable Interrupt: The hardware which cannot be delayed and should process by the processor immediately.

Which method deals with multiple types of exceptions and interrupts?

polled exception handling
Dealing with multiple types of exceptions and interrupts This is called polled exception handling. The processor can branch to a different address for each type of exception.

What is the difference between an interrupt and an exception?

Exceptions and interrupts are unexpected events that disrupt the normal flow of instruction execution. An exception is an unexpected event from within the processor. An interrupt is an unexpected event from outside the processor. You are to implement exception and interrupt handling in your multicycle CPU design.

When does an interrupt occur in a program?

Software interrupts are referred as synchronous exceptions. Synchronous exceptions always occur when event reached to a certain statement in the source code.

Why is there an exception in the handler?

The handler may have been invoked for a number of reasons. The handler thus needs to determine the cause of the exception or interrupt. Information about what caused the exception or interrupt can be stored in dedicated registers or at predefined addresses in memory. Next, the exception or interrupt needs to be serviced.

What’s the difference between interrupt, TRAP, fault and abort?

There are 4 classes of Exception- interrupt, trap, fault and abort. Though, interrupt belongs to exception still there are many differences between them. In any computer, during its normal execution of a program, there could be events that can cause the CPU to temporarily halt.
