What are the two types of interrupts?

Types of Interrupts:

  • Hardware Interrupts: If the signal for the processor is from external device or hardware is called hardware interrupts.
  • Software Interrupts: Software interrupt can also divided in to two types.

In this regard, how is a software interrupt initiated?

Soft interrupts are not initiated by a hardware device; they are initiated by software. Handlers for these interrupts must also be added to and removed from the system. Consequently, the interrupt handler must avoid involving itself in an activity (such as acquiring a mutex) that might cause it to sleep.

What are the software interrupts in 8085?

The software interrupts are program instructions. When the instruction is executed, the processor executes an interrupt service routine stored in the vector address of the software interrupt instruction. The software interrupts of 8085 are RST 0, RST 1, RST 2, RST 3, RST 4, RST 5, RST 6 and RST 7.

What is the program interrupt?

An interrupt is a signal from a device attached to a computer or from a program within the computer that requires the operating system to stop and figure out what to do next.
