Boost Processor Efficiency and Support Interrupt Virtualization

A Generic Interrupt Controller (GIC) is an exclusive block of IP that performs critical interrupt management, prioritization and routing. GICs are primarily used for boosting processor efficiency and supporting interrupt virtualization. Arm has several generic interrupt controllers that provide a range of interrupt management solutions for all types of Arm Cortex multiprocessor systems.

Features and Benefits

Designed for Interrupt Management in Distributed Virtualized Systems

Arm GIC provides a scalable high-performance interrupt delivery to virtual machines in multi-chiplet/socket platforms to enable powerful infrastructure SoCs.

Optimized for Virtualization

Arm offers a high-performance path for accelerator interrupts to be delivered to virtual machines.

Linux Support

Arm CoreLink SMMU and GIC are supported on the main open source Linux platform and the latest architecture provides further enhancement to IO virtualization.

Automotive Safety Ready

Arm offers CoreLink GIC-600AE and MMU-600AE, designed to enable high-performance systems for automotive use cases, targeting ASIL B to ASIL D safety integrity levels.
