Responsible for All Aspects of IO Memory Management
A system memory management unit (SMMU) handles all aspects of IO memory management, including address translation caching and hardware driven memory page table walks. 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
Arm SMMUs provide scalable, high-performance IO accelerators to be used in virtualized edge-to-cloud platforms. Arm’s MMU-700 supports custom on-die accelerators with Root Complex integrated endpoint virtualization.
Arm offers a high-performance path to memory and enables heterogeneous solutions that blend compute and acceleration to provide the optimal platform for virtualized workloads.
Arm CoreLink SMMU and GIC are supported on the main open source Linux platform and the latest architecture provides further enhancement to IO virtualization.
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.
The System Memory Management Unit Family
Arm SMMU v3.2 compliant MMU-700 is compatible with Arm v8.4 and v9 CPU’s. It enables virtualization in the Arm Secure World and QoS for IO traffic. MMU-700 is built for PCIe Gen5 BW.
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 the Arm Safety Ready program.
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.
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.
