What is an interrupt controller IP?

An interrupt controller IP is a hardware block that manages interrupt signals generated by peripherals and internal system events in SoCs and ASICs.

It prioritizes interrupts, routes them to the appropriate processor cores, and ensures timely handling of critical events.

Main functions of interrupt controller IP

Interrupt prioritization

The controller assigns priority levels to different interrupt sources, ensuring that critical events are handled first.

Interrupt routing

Interrupt signals are routed to specific processor cores, supporting efficient multi-core operation.

Interrupt masking and control

The IP allows selective enabling and disabling of interrupts, providing flexibility in system control.

Low-latency response

Optimized architectures ensure minimal latency between interrupt generation and processing.

Types of interrupt controllers

Basic interrupt controllers

Suitable for simple embedded systems with limited interrupt sources.

Advanced interrupt controllers (e.g., GIC)

Advanced controllers such as Generic Interrupt Controller (GIC) support multi-core systems, virtualization, and complex priority schemes.

Distributed interrupt controllers

Distributed architectures provide scalability and improved performance in large SoC designs.
