There are three registers, an Interrupt Mask Register (IMR), an Interrupt Request Register (IRR), and an In-Service Register (ISR ). the IRR maintains a mask of the current interrupts that are pending acknowledgement, the ISR maintains a mask of the interrupts that are pending an EOI, and the IMR maintains a mask

hardware , device interruptions are designed to implement asynchronous function calls, therefore, the operating system itself is highly dependent on them. APC is not discussed here for the time being. I will have the opportunity to write more articles for further discussion DPC functions as ISR (Interrupt ServiceRoutine. Just because ISR splits some functions out of the operating system and puts them i
