This chapter elaborates on the concept of interrupt-driven I/O in computer organization, detailing its necessity over programmed I/O. It explains the sequence of events that occur during interrupt processing, emphasizing the importance of context switching, interrupt service routines, and the handling of processor states during interruptions. The chapter concludes with a focus on the advantages of interrupt-driven systems in enhancing CPU efficiency and reducing idle time.
Interrupt-driven I/O significantly reduces CPU busy waiting, allowing the processor to perform other tasks while waiting for I/O operations to complete.
Effective handling of interrupts necessitates the preservation and restoration of processor context using a system stack.
The interaction between hardware and software in interrupt processing provides a balanced approach to manage system resources efficiently.
A method of input/output processing that allows the CPU to perform other tasks while waiting for I/O operations to complete, initiated by an interrupt signal.
The process of saving the state of a CPU so that it can be restored and execution resumed from the same point later.
A special block of code that is executed in response to an interrupt, responsible for handling the interrupt and performing necessary data transfers.
A word containing the status information of the currently running program, including result flags and control information.
