ARMv9: this is the architecture of the next generation | Digital Trends Spanish


ARM Holdings announced the new ARMv9 architecture, which comes to replace the ARMv8 scheme after 10 years on the market.

The company highlighted that the new architecture will allow improvements of up to 30 percent in the performance of the processors, as well as greater security integrated into the hardware. ARM Holdings said that the first chips with the ARMv9 architecture will be presented this year at smartphones, with the first models on the market in 2022.

The architecture of a processor defines how a chip works, what it can do, and how it accesses memory. In this sense, an architecture change marks a milestone in electronic device capabilities, so we could eventually see new hardware designs and novel features.

The three pillars of ARMv9

According to ARM, the new ARMv9 architecture is centered on three principles: computing power, security, and artificial intelligence processing.

Regarding power, ARM said the new architecture will allow performance increases of 30 percent in the CPUs of mobile devices. However, the company did not provide details of how this improvement will be achieved.

Where he did give details is in the improvement in the processing of artificial intelligence data. ARM Holdings said that the new architecture will feature a feature called the Scalable Vector Extension (SVE), which will allow for faster processing of virtual or augmented reality data, and artificial intelligence through a 5G connection. The company explained that SVE is based on a standard from the Fugaku supercomputer, the most powerful in the world.

Regarding security, ARM Holdings explained that this will be achieved to a greater extent in memory labeling (a function used by Android 11) and a function called Confidential Computing Architecture (CCA), which broadly allows applications to run in an environment isolated from the main operating system and other applications. A simile would be the Linux containers, although with the difference that the CCA runs at the hardware level.

ARM mentioned that the first processors with the ARMv9 architecture will be available until 2022 in the Cortex-A line for smartphones. Some reports say that Apple’s A15 Bionic chip, which will integrate the iPhone 13, will have this architecture.
