WebAs illustrated in Figure1, the ARM generic interrupt controller (GIC) is a part of the ARM A9 MPCORE proces-sor. The GIC is connected to the IRQ interrupt signals of all I/O peripheral devices that are capable of generating interrupts. Most of these devices are normally external to the A9 MPCORE, and some are internal peripherals (such as timers). WebThe following diagram shows a GIC taking interrupts from n different peripherals, and distributing them to two different processors. Figure 1. GIC example. The GIC is the standard interrupt controller for Arm Cortex-A and Arm Cortex-R profile processors. The GIC provides a flexible and scalable approach to interrupt management, supporting ...
