What is the difference between vector and non-vectored interrupt?
Vectored Interrupts are those which have fixed vector address (starting address of sub-routine) and after executing these, program control is transferred to that address. Non-Vectored Interrupts are those in which vector address is not predefined.
What is a non-vectored interrupt?
Non-Vectored Interrupts (Scalar Interrupt) are those in which vector address is not predefined. The interrupting device gives the address of sub-routine for these interrupts. INTR is the only non-vectored interrupt in 8085 microprocessor.
What is vectored interrupt mechanism?
In a computer, a vectored interrupt is an I/O interrupt that tells the part of the computer that handles I/O interrupts at the hardware level that a request for attention from an I/O device has been received and and also identifies the device that sent the request.
What is the difference between a polled and vectored interrupt system?
The main difference between interrupt and polling is that in interrupt, the device notifies the CPU that it requires attention while, in polling, the CPU continuously checks the status of the devices to find whether they require attention. In brief, an interrupt is asynchronous whereas polling is synchronous.
What is the difference between maskable and non maskable interrupts?
Maskable interrupt is a hardware Interrupt that can be disabled or ignored by the instructions of CPU. A non-maskable interrupt is a hardware interrupt that cannot be disabled or ignored by the instructions of CPU.
What are the two main types of interrupts?
Interrupts have two types: Hardware interrupt and Software interrupt. The hardware interrupt occurrs by the interrupt request signal from peripheral circuits. On the other hand, the software interrupt occurrs by executing a dedicated instruction.
What are the three types of interrupts?
Types of Interrupts
- Internal Interrupt.
- Software Interrupt.
- External Interrupt.
