Real time applications such as space or automotive where instant autonomous decision making is crucial require configurable standardized interrupt controllers. There are many well-known examples such as the Global Interrupt Controller (GIC) for Cortex-A, Nested Vectored Interrupt Controller (NVIC) for Cortex-M, Platform Level Interrupt Controller (PLIC) or Core Local Interruptor (CLINT) for RISC‑V, etc., and some vendors introduce their own custom interrupt controllers working on top of the standard ones.
