WebIn multiprocessor systems, an interrupt will usually only interrupt one of the CPUs. (As a special cases mainframes have hardware channels which can deal with multiple interrupts without support from the main CPU.) The hardware interrupt interrupts the CPU directly. This will cause the relevant code in the kernel process to be triggered. WebIn contrast, an interrupt triggers the CPU to perform the interrupt handler routine. A trap is synchronous and may occur after the execution of the instruction. In contrast, an interrupt is asynchronous and may occur at any time. A trap is generated by a user program instruction. In contrast, the hardware devices generate an interrupt.

WebApr 8, 2013 · This means that all available interrupts within a processor have an associated interrupt level, which is the priority of that interrupt within the system. Typically, interrupts starting at level “1” are the highest priority within the system and incrementally from there (2, 3, 4, etc.) the priorities of the associated interrupts decrease.
