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 Powerful Infrastructures

Arm provides a scalable high performance coherent backplane IP to enable partners to build more powerful infrastructure SoCs from edge to cloud. 

Optimized for Virtualization

Arm offers a high-performance path to memory and enables heterogeneous solutions that blend compute and acceleration providing the optimal platform for virtualization workload. 

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 automotive enhanced GIC and SMMU, designed to enable high performance systems, targeting ASIL B to ASIL D safety integrity levels.
