Interrupt chaining improves efficiency by linking multiple interrupts in a sequence, allowing the processor to address each request as soon as it finishes servicing the previous one. This minimizes the delay between processing consecutive interrupts and ensures that no requests are overlooked.

There are two approaches how to call interrupt handlers for child devices in IRQ handler of parent (interrupt controller) device. Chained interrupts: "chained" means that those interrupts are just chain of function calls (for example, SoC's GPIO module interrupt handler is being called from GIC interrupt handler, just as a function call ...

Computer Architecture: Interrupts. Data transfer between the CPU and the peripherals is initiated by the CPU. But the CPU cannot start the transfer unless the peripheral is ready to communicate with the CPU. When a device is ready to communicate with the CPU, it generates an interrupt signal.

Understanding priority interrupts, software polling, and daisy chaining is crucial for effective system design, particularly in real-time systems. Explore this System design course for insights into managing interrupts and improving system responsiveness. HARDWARE METHOD – DAISY CHAINING.

By managing the inter-action with external systems through effective use of interrupts can dramatically improve system efficiency and the use of processing resources. The actual process of determining a good handling method can be complicated, challenging and fun.
