Arm announces Armv9, a chip designed for security and AI

A decade after the release of Armv8, Arm has announced the next version of the chip architecture.

In comparison to the previous release, Armv9 offers improvements in the following areas:

  • AI performance
  • Security
  • Overall performance optimisation

Arm’s technology powers almost every smartphone on the market today (including certain laptops and servers), which makes this an important milestone.

Last year, Apple announced that Mac computers are making the transition to Arm-based processors, and the same holds true for Apple Silicon Macs.

Across the industry, this is by no means a lone case, as other manufacturers such as Microsoft have also released laptops that integrate Arm processors during the last couple of years.

Above all else, Armv9 is praised for improvements in the security department.

This is partly thanks to the new Arm Confidential Compute Architecture (CCA).

This is essentially an attempt to protect data of a sensitive nature by using a hardware-based approach.

This allows certain bits and pieces of code to be separated from the rest of the system through the so-called ‘Realms’ that can be dynamically allocated.

Next, we have Scalable Vector Extension 2 (SVE2), which will play an important role in AI processing and machine learning.

This should provide benefits to the following areas:

  • Voice recognition
  • Image processing
  • 5G systems
  • Virtual and augmented reality

Last but not least, Armv9 also promises to deliver a general performance boost.

Over the next two generations, CPU performance is expected to increase by more than 30%, with further software and hardware optimisations increasing it even more.

According to Arm, all software should have no issues running on Armv9-based processors.

The company expects to start shipping the new technology before the end of the year.
