ARM just showed 2021's smartphone CPUs, led by the powerful Cortex-X1

PCWorld

Like the prior Cortex-A77, the Cortex-A78 will consist of what ARM calls its big.LITTLE octacore architecture, with four high-performance A78 cores and four A55 cores optimized for long battery life. ARM said that a Cortex-A78 core running at 3GHz would deliver 20 percent more sustained, single-core performance than the Cortex-A77 core running at 2.6GHz, assuming 1 watt per core. The performance is based on simulated estimates. Alternatively, a phone maker could clock the A78 to consume half the power at the same performance as the A77, Williamson said. ARM believes that the octacore Cortex-A78 layout will require 15 percent less die space than the Cortex-A77, leading to smaller phones.


Arm unveils 2 new AI edge computing chips

#artificialintelligence

Semiconductor and software design company Arm is doubling down on edge AI hardware, a market that's expected to be worth $1.15 billion by 2023. It today announced two new AI-capable processors -- the Arm Cortex-M55 and Ethos-U55, a neural processing unit (NPU) -- designed for internet of things (IoT) endpoint devices, alongside supporting software libraries, toolchains, and models. The company claims that the two chips, which are expected to arrive in market in early 2021, together will deliver an uplift of up to 480 times in machine learning performance in certain voice and vision scenarios. "[Machine learning] processing on low-power endpoint devices is critical to realizing the full potential of AI for IoT," wrote the company in press materials. "An extended range of advanced hardware capabilities is required to enable innovation and scale."

Arm has announced details of its latest processors designed for artificial intelligence and machine learning, the Arm Cortex-M55, as well as the first microNPU (Neural Processing Unit), the Ethos-U55 which offer a combined 480x machine learning improvement for microcontrollers. Cortex-M based processors are already powering a vast range of AI products with over 50 billion chips shipped to partners. Arm claims that its latest Cortex-M55 is its most capable AI processor yet and is the company's first Cortex-M processor to be based on the Armv8.1-M Equipped with Arm Helium vector processing technology, the Cortex-M55 offers significantly enhanced energy-efficient, 5x digital signal processing (DSP) performance improvement and 15x machine learning (ML) performance compared to previous Cortex-M generations. In addition, custom instructions will be added to improve processor performance for specific workloads, which is a new feature for Cortex-M series processors.


EETimes - Arm Leaps Into TinyML With New Cores -

#artificialintelligence

Arm has unveiled two new IP cores designed to power machine learning in endpoint devices, IoT devices and other low-power, cost-sensitive applications. The Cortex-M55 microcontroller core is the first to use Arm's Helium vector processing technology, while the Ethos-U55 machine learning accelerator is a micro-version of the company's existing Ethos NPU (neural processing unit) family. The two cores are designed to be used together, though they can also be used separately. Enabling AI and machine learning applications on microcontrollers and other cost-sensitive, low-power resource-constrained devices is known as the tinyML sector. With the rise of 5G initiating a trend for more intelligence in endpoint devices, tinyML is expected to grow exponentially into a market that encompasses billions of consumer and industrial systems.


ARM's new edge AI chips promise IoT devices that won't need the cloud

#artificialintelligence

Edge AI is one of the biggest trends in chip technology. These are chips that run AI processing on the edge -- or, in other words, on a device without a cloud connection. Apple recently bought a company that specializes in it, Google's Coral initiative is meant to make it easier, and chipmaker ARM has already been working on it for years. Now, ARM is expanding its efforts in the field with two new chip designs: the Arm Cortex-M55 and the Ethos-U55, a neural processing unit meant to pair with the Cortex-M55 for more demanding use cases. The benefits of edge AI are clear: running AI processing on a device itself, instead of in a remote server, offers big benefits to privacy and speed when it comes to handling these requests.
