Responsible for All Aspects of Memory Management

A system memory management unit (SMMU) handles all aspects of memory management, including caching and memory virtualization. It enforces memory protection and access, and is designed for use in a virtualized system where multiple guest operating systems are managed by a hypervisor.

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.

The System Memory Management Unit Family

Software compatible with MMU-600 and additional safety features targeting ASIL B to ASIL D systems including fault management unit for error detection and reporting. The CoreLink MMU-600AE is part of Arm’s Safety Ready program

CoreLink MMU-600

Highly scalable with support for millions of translation contexts. Designs can be scaled from small to large-scale systems while maintaining a common driver framework. TrustZone Media Protection protects high-value 4K premium content.

Technical Reference Manual
CoreLink MMU-500

The CoreLink MMU-500 is compatible with a wide range of bus master types and capabilities, offering maximum flexibility in implementing efficient SoC designs that need to support virtualized applications.

Technical Reference Manual
CoreLink MMU-401

The CoreLink MMU-401 offers stage 2 accelerated address translation for bus masters that already implement MMU functionality for stage 1 translation, such as the Mali-400 Graphics Processor, thereby reducing the hypervisor overhead in managing complex bus master interactions.
