Security is increasingly becoming more relevant, as the vulnerability surface grows along with the number of connected devices. Arm has prioritized security for many years, introducing TrustZone® as a security hardware architecture in 2003. One key TrustZone feature…

Architectural Simulators

Architecture simulators of various kinds are a key tool in the computer architecture toolbox. They provide a convenient model of real hardware, such as a CPU or even a whole System on Chip (SoC), at a level of abstraction that…

Core counts continue to increase for High-Performance Computing (HPC) systems, but multiple factors may prevent current software from fully utilizing the increased available thread count. Inter-thread communication and serialized execution may hamper…

One of the main issues in High-Performance Computing (HPC) systems is the underutilization of resources. Parallel applications partition and distribute compute and data across processors in the system that work together to solve a given problem. In this…

Temporal data prefetching usually introduces huge on- and off-chip storage and traffic overheads, making them impractical. However, a novel solution proposed by Arm Research and The University of Texas at…

This February I attended the Symposium on High-Performance Computer Architecture (HPCA) in Washington D.C, which celebrated its 25th anniversary this year. To commemorate the occasion, a special mention was made to Laxmi Bhuyan, Yale Patt and Dharma Agrawal, the organisers…

In this blog series, we take a look back at some of the highlights from last year's Arm Research Summit. Interested in attending this year? Find out more here.

Yungang Bao from the Chinese Academy of Sciences joined us to make his case for labeled computer…

In the previous posts in this blog series we looked at how the Armv8.1-M architecture with Arm Helium technology (also known as MVE) handles vector instructions. The problem is that whenever code is vectorized it’s not long before Amdahl's law sneaks up…

When we designed the M‑Profile Vector Extensions (MVE), known as Arm Helium technology for the Arm Cortex-M processor series, we wanted to make it a good fit for a wide variety of digital signal processing (DSP) applications. The ability to perform computation…

In the first part of this blog series, I explained the “beatwise” execution that’s at the heart of Helium technology (also known as the M-profile Vector Extensions / MVE). There’s some useful background information in that post, so it’s worth looking at…

Today, we’re excited about the announcement of the M‑profile vector extensions (MVE) for the Armv8‑M, which started in Arm’s research group several years ago. When we were asked to increase the DSP performance of
Arm Cortex‑M processors, naturally…

Arm Research is responsible for delivering a clear vision of disruptive and emerging technologies and how they may affect our future. This disruptive technology landscape is used to develop our research strategy, which guides internal research, external…

Fixed functional hardware accelerators are specialised hardware units, meant to carry out a particular task faster than is possible in software running on a general-purpose CPU. They have been researched for many years, and it is well understood that…

The Arm Scalable Vector Extension (SVE) is a key technology for Arm processors to efficiently address the increasing computation requirements of future high-performance computing (HPC), data analytics and…

Over the last few years, there’s been a terrific amount of interest in artificial intelligence, and specifically the branch of machine learning known as 'deep learning'. To help computer architects get “up to speed” on deep learning, I co…

This is the first in a two-part post from Arm Principal Researcher Dr Nathan Chong on his joint research with Tyler Sorensen (Imperial College London) and Dr John Wickerson (Research Fellow, Imperial College London). This research was published as a PLDI…
