ARM announces ARMv9 chip architecture, 1st since 2011

ARM has just introduced the latest processor architecture ARMv9 with important improvements compared to the ARMv8 standard presented in 2011. It is, therefore, an extremely important announcement that introduced us to new architecture for chipsets.

We underline that ARM has a wide presence in the mobile device market with virtually the entire industry mobile to use its ARMv8 architecture in the manufacture of processors. From Qualcomm to Samsung, the plant drawn up by ARM defines the industry.

The current standard, ARMv8 arrived in 2011 and, in the last 5 years alone, more than 100 billion mobile devices use this standard in their components. This is the language that dictates the functioning of the current processors of our smartphones.

ARM now prepares the industry for a new generation of processors optimized for the performance, safety e Artificial intelligence (IA), as well as the compatibility with the previous generation and all the configurations created for this one.

CCA reinforces security in ARMv9 architecture

O “machine learning“and above all security, it is complied with the Confidential Compute Architecture, CCA. It is a secure environment, based on hardware, that comes to protect the code (software), even of software with privileged access.

This CCA aims to prevent hardware security breaches and prevent vulnerabilities such as Specter and Meltdown.

For this purpose, ARM will create “Realms” with v9 that will be created by the applications as needed. They are small “realms” where the application can be run safely, in a controlled environment where not even the operating system interferes.

In summary, even if the operating system is out of date, or has a security vulnerability, applications can continue to operate safely. By extension, the code of the apps and information will also be secure.

ARM also revealed the fruits of its work with Fujitsu, a partner that helped it create the Scalable Vector Extension (EVS). The new vector was requested by Fujitsu for its new supercomputer.

Machine learning will benefit from ARM’s SVE2.

Furthermore, with ARMv9 we have SVE2, the second generation that will enhance the processing between GPU, CPU and NPU. This will translate into a huge leap in the capabilities of artificial intelligence and the evolution of the machine learning.

The first ARMv9 processing cores are being designed

The next generations of cores perform better.

According to ARM, the first two generations of ARM v9 cores for CPUs are already being designed. This second generation should present performance improvements of around 30% compared to current Cortex models.

We also emphasize that the new generations of ARMv9 cores are called Matterhorn and Makalu.

More specifically, Makalu will be the first Cortex-A core to give up support for 32-bit software. Something that shouldn’t matter to users since the Google Play Store stopped accepting 32-bit apps several years ago.

In fact, as of August 1, 2021, the Play Store will remove any 32-bit content (applications), supporting only 64-bit apps and devices as far as the processing architecture is concerned.

Ray Tracing technology will reach smartphone printers

Ray Tracing will arrive on smartphones with the new generation.

For players mobile it’s great news. Ray tracing simulates the natural incidence of light, light beams in the real world, being one of the highlights of the new PS5 and XBX. In the future it will also reach mobile devices with Mali graphics.

ARM v9 architecture is extremely important

Note that a new processor architecture dictates, for example, how RAM is used, in what order and with what priority. It is this architecture that tells the processor how to work, what resources to use and how to “communicate”.

In view of the above, it is understandable that a new standard does not appear every year taking into account the ramifications and impact caused in the most diverse sectors of the industry. However, since the ARMv8 architecture arrived in 2011, it already needed updates.

With regard to this, when ARMv8 was launched, it brought innovations such as support for AArch64. This 64-bit instruction set would unlock a new evolutionary leap in processing capacity compared to the previous version, ARMv7 limited to 32-bits.
