The TZMP2 system uses main-side filtering to avoid a large amount of system memory split for protective media, eliminating the need for the CoreLink MMU-600 to allocate dedicated memory space as it is currently powered up, saving on each device About $ 3, saving more than $ 1 billion for the entire industry, given the number of devices sold worldwide.
The CoreLink MMU-600 is redesigned to be compatible with the Armv8.2 Page Tables based on the Arm SMMUv3.1 specifications CoreLink MMU-600 supports phase-1 and / or phase-2 transitions as defined by Arm Distributed Virtual Memory (DVM) The mechanism extends all core device virtualization and protection to non-core accelerators and devices so that each accelerator driver runs in its own domain. Page tables shared with core devices simplify memory between CPUs and non-CPU devices management.
In response to new marketplace applications such as premium content protection, the microarchitecture of the CoreLink MMU-600 has been rebuilt and redesigned, resulting in dramatic improvements in design: Media Protection> 3x Area ~ 0.5x Working frequency (1.6 times)
The CoreLink MMU-600 also helps simplify the definition of system architecture, especially when integrating with coherent accelerators because the primary side filters ensure that unauthorized access is filtered at the accelerator's borders to prevent leakage.
Internet of Trust, a security consulting firm working on the GlobalPlatform TEE certification program, evaluated the level of security based on the TZMP2 security level and the TrustZone-based TEE architecture.According to chief technology officer Carolina Lavatelli, the results show that Arm TZMP2 is designed to provide a level of security equivalent to that of TEE-based solutions in media pipelines managed by credible worlds.
The TZMP2 technology with the CoreLink MMU-600 is gaining recognition from the industry giants who are very interested in technology that will ensure media content is not infringed by copyright infringement. Here's what a key figure in the movie industry is saying:
'Arm CoreLink MMU-600 offers a more flexible and lower cost solution based on a standard system architecture and security model and we expect this lower cost and more flexible turnkey solution will make it easier for companies around the world An effective solution for high-quality video and VR content. "- Ian Harvey, Senior Vice President, Advanced Technology, Twentieth Century Fox
In addition to the CoreLink MMU-600, Arm also announced the Mali-D71, a next-generation display processor that manages address translation with the CoreLink MMU-600 for memory access. The combination of Mali-D71 and CoreLink MMU-600 is secure for consumers and High-quality visual experience, even for the most demanding high frame rate next generation 4K display as well.
