ARM to boost processor performance by 50x with new AI instructions

ARM's Dynamiq chip designs enable new kinds of multicore processing

Tech giant ARM Holdings today entered the race to power driverless cars as it launched a new chip - one of the first big innovations since the Cambridge company was snapped up for £24 billion by Japan's SoftBank a year ago. So for example, when a smartphone user starts playing a video game with intensive graphics, the chip will fire up those larger CPUs, and then when they stop playing, will wind the bigger cores back down.

ARM was light on the specific details of how DynamIQ would be implemented or when we can expect to see it in-market, but the company clearly isn't standing still when it comes to innovating on its mobile hardware.

With that in mind, ARM is announcing its DynamIQ architecture, which it labels "Multicore Redefined".

The introduction of DynamIQ is an evolutionary step forward for ARM big.LITTLE technology which revolutionized multi-core characteristics for our primary compute devices when launched in 2011. Rather than having four Cortex-A73 cores in one cluster and four low power A53s in another, with DynamIQ SoC designers can pair any combination of ARM cores, such as the A73, A72, A53, etc together on a single cluster with a shared a memory pool. ARM has also redesigned the memory subsystem (shared across all cores) to not only improve power management, but to also to speed up data access.

Importantly, each CPU core's voltage, operating frequency, and sleep state can be controlled individually, which allows for fine-grain control over performance and power consumption.

Safer autonomous systems: DynamIQ brings greater levels of responsiveness for ADAS solution and increased safety capabilities which will enable partners to build ASIL-D compliant systems for safe operation under failure conditions. This move has should net increased performance, power efficiency, and reliability. On that last point, ARM says that this performance boost will be a boon to computer vision and machine learning systems.

ARM has just announced its latest ARM DynamIQ technology for future Cortex-A processors, which looks to support the growing adoption for artificial intelligence (AI) and machine learning (ML) in just about everything from smartphones to autonomous systems.

ARM hopes that leveraging DynamIQ architecture will allow its designs to be shipped in over 100 billion chips between now and the year 2021.
