VECTOR INTERRUPT

If the interrupt is assigned to any predefined branching address to its ISR it is termed as vector interrupt.

NON VECTOR INTERRUPT

If the interrupt is not assigned to any predefined branching address to its ISR it is termed as non-vector interrupt.

PRIYAKRISH

An interrupt vector is the memory address of an interrupt handler, or an index into an array called an interrupt vector table or dispatch table. Interrupt vector tables contain the memory addresses of interrupt handlers. When an interrupt is generated, the processor saves its execution state via a context switch, and begins execution of the interrupt handler at the interrupt vector.

In the 8086/8088, the interrupt vector table is the first 1024 bytes of memory. In the 8085, the interrupt vector table is the first 64 bytes of memory if using the RST form of interrupt, otherwise the interrupt vector is provided by the interrupting device, usually in the form of a CALL instruction.

The interrupt handler is wherever the interrupt vector points to.

Yes, the interrupt vector is inside the kernel.

If the interrupt is not assigned any predefined branching address to its ISR it is termed as non interrupt vector
