Arm announces new architecture 'Arm v9', what are the added features?



The high-performance chip '

M1 ' developed by Apple and Qualcomm's SoC ' Snapdragon ' series adopted in many Android terminals adopt the ' Arm architecture ' developed by ARM Holdings as the CPU architecture. 'Armv9 ', the new architecture of Arm architecture for the first time in 10 years, was announced on March 30, 2021.

According to ARM Holdings, shipments of chips using the Arm architecture continue to increase, with more than 100 billion Arm architecture-based devices shipped over the past five years. Simon Segars, CEO of ARM Holdings, said, 'With an eye on the future that AI will shape, we need to build a state-of-the-art computing platform to prepare for the unparalleled challenges that will come. The answer is Armv9, 'he said, announcing the new architecture Armv9.

CEO Cigars said of Armv9, 'As the core of the 300 billion Arm-based chips that will be shipped in the future, it will be widely used for security while combining the economics, design freedom, and availability of general-purpose computing. We will continue to meet the demand for powerful application-specific processing, 'he said, highlighting the enhancements in terms of security and process technology.

◆ Security
Richard Grissenswait, chief architect of ARM Holdings, points out that the biggest challenge in computing is 'security.' On top of that, we announced that Armv9 will introduce the security technology 'Arm Confidential Compute Architecture (CCA)' that enables operations in a hardware-based secure environment. CCA is a technology that prevents all software, including privileged software, from accessing or making changes to data, which 'makes the computing infrastructure much more reliable,' Grissenswait said. I am.

According to Grissenswaite, CCA uses a concept called 'Realm ' that is separate from the OS and hypervisor. By managing data using Realm, each application can reliably protect data even if the OS is destroyed.



'We have faced security risks due to insecure memory over the last few decades,' Grissenswaite said. Armv9 is equipped with a memory safety verification system ' Memory Tagging Extension (MTE) ' jointly developed with Google, and announced that it will be supported by

Android 11 and openSUSE.



◆ SVE2
According to ARM Holdings, it is expected that more than 8 billion AI-enabled voice assistant devices will be used worldwide by 2020, and that more than 90% of the software shipped will contain AI elements. That thing. 'In the current situation where AI is used for various purposes, there is a need for application-specific solutions,' he said, emphasizing the need for a computational processing system that can be adapted to various applications.

Armv9 is to apply for a variety of applications, the world's fastest supercomputer '

Fugaku support the core of the' 'Scalable Vector Extension (SVE)' extended 'SVE2' thing to be equipped with the. 'SVE2 improves computing performance in a wide range of applications such as image processing, 5G systems, VR, AR, and machine learning,' Grissenswait said.



In addition, ARM Holdings is working on improving frequency, bandwidth, cache size and reducing memory latency, and plans to improve the performance of Armv9 base CPU by 30% or more compared

to the current CPU.



'Armv9 fills the gap between hardware and software, allowing developers to build and program a reliable computing platform for the future, while leveraging standardization,' said Grissenswait. This will allow Arm partners to combine faster time-to-market and cost control with greater development capabilities for their own solutions, 'said Armv9 with an architecture that benefits both developers and users. It emphasizes that there is.
