Current solutions to improve virtual to physical translation performance are impractical. We present an alternative, where a small change has a significant impact.
Speculative Vectorization with Selective Replay
Arm Research are investigating a hardware-software codesign solution to support auto-vectorization, called Speculative Vectorization with Selective Replay.
Simplifying persistent programming with microarchitectural support
Hardware-based coherence has simplified concurrent programming, and our work shows the improvements in performance and programmability.
University of Cambridge: Partners in Parallel
When Dr. Timothy Jones finished his PhD and was looking to establish his career, one email to Arm changed everything. It led to new collaborators, invaluable industry insight and a high-level mentor.
Fused: Closed-loop Performance and Energy Simulation of Embedded Systems
New IoT applications to bridge the cyber and physical world are driving a need for smaller and lower-cost devices. Arm Research proposes Fused, targeting energy-driven embedded systems.
Running Trusted Firmware-A on gem5
Arm has prioritised security, introducing TrustZone. A key component of TrustZone is the Secure Monitor, providing context switching between REE and TEE.
SCALE-Sim: A cycle-accurate NPU simulator for your research experiments
Architecture simulators are a key tool in the computer architecture toolbox. They provide a convenient model of real hardware at a level of abstraction that makes them faster and more flexible than low…
Tasking Lives Up To Its Promises
Tasking could help overcome a major resource underutilization issue in High-Performance Computing, When parallel applications partition and distribute compute and data across processors in the system,…
Characterization of Multi-threaded HPC Codes
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…
Making Temporal Prefetchers Practical: The MISB Prefetcher
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…
Research in a Post-Moore Era: HPCA 2019
This February I attended the Symposium on High-Performance Computer Architecture (HPCA) in Washington D.C, which celebrated its 25th anniversary this year. Apart from being a milestone HPCA, this year…
The Case for Labeled Computer Architecture
Yungang Bao from the Chinese Academy of Sciences joined us at last year's Arm Research Summit to make his case for labeled computer architecture.
Making Helium: Bringing Amdahl's law to heel (4/4)
In previous posts we've looked at how Arm Helium technology handles vector instructions. The problem is that whenever code is vectorized, it’s not long before Amdahl's law sneaks up on you! Amdahl's law…
Making Helium: Going around in circles (3/4)
The ability to perform computation on data efficiently is only half the story when it comes to new Arm Helium technology. Equally important is the ability to access and store this data in memory.
Making Helium: Sudoku, registers and rabbits (2/4)
Beatwise execution is at the heart of Helium technology. In the second part of a four-part series, we explore how new M-profile vector extensions efficiently handle different data formats.
Making Helium: Why not just add Neon? (1/4)
Today Arm announced 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…
Enabling hardware accelerator and SoC design space exploration
Fixed functional hardware accelerators have been researched for many years, and it is well understood that they improve the performance and energy efficiency of a system. Integrating hardware accelerators…
The Arm Research Workshop on Novel Algorithms
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…
