Interrupt handler - Wikipedia

WebInterrupt handler. In computer systems programming, an interrupt handler, also known as an interrupt service routine or ISR, is a special block of code associated with a specific interrupt condition. Interrupt handlers are initiated by hardware interrupts, software interrupt instructions, or software exceptions, and are used for implementing ... WebNov 26, 2024 · Interrupt processing. Step 1 − First device issues interrupt to CPU. Step 2 − Then, the CPU finishes execution of current instruction. Step 3 − CPU tests for pending interrupt request. If there is one, it sends an acknowledgment to the device which removes its interrupt signal. Step 4 − CPU saves program status word onto control stack. grp finance hub https://oianko.com
