Define vectored and non-vectored interrupt
WebApr 16, 2024 · 3. If the hardware supports vectored interrupts, there is no reason not to use them. This is more a question of implementation cost (vector tables and prioritisation logic) vs software cost (reading status registers and looking up the correct vector). As hardware has become cheaper over time, it makes sense to have dedicated logic to … WebThe important feature of a vectored interrupt is that the device itself provides the interrupt vector address. With non-vectored interrupts, all devices using the same interrupt request routine will transfer control to the same location, and the interrupt service routine will have to figure out which of the possible devices is actually interrupting.

WebJan 29, 2024 · A non-vectored interrupt is where the interrupting device never sends an interrupt vector. An interrupt is received by the CPU, and it jumps the program counter to a fixed address in hardware. This is literally a hard coded ISR which is device agnostic.
