WebWhile interrupts and polling carry out similar processing, there is a notable difference. Where interrupts are used, the MCU is immediately alerted when an event occurs, and can quickly switch to the requested processing. This rapid responsiveness is often referred to as real-time processing. Interrupts are commonly used by hardware devices to indicate electronic or physical state changes that require time-sensitive attention. Interrupts are also commonly used to implement computer multitasking, especially in real-time computing. Systems that use interrupts in these ways are said to be interrupt-driven. [3] See more In digital computers, an interrupt (sometimes referred to as a trap) is a request for the processor to interrupt currently executing code (when permitted), so that the event can be processed in a timely manner. If … See more Each interrupt signal input is designed to be triggered by either a logic signal level or a particular signal edge (level transition). Level … See more Interrupts may be implemented in hardware as a distinct component with control lines, or they may be integrated into the memory subsystem .
