Architectures and Processors blog

Upstream gem5 and ATP-Engine MPAM-style cache partitioning are discussed, with experiments for the feature being proposed and analyzed.

This blog covers techniques and tips that are useful to create better performing programs through compilers whether you are creating Android, Desktop or Server applications.

In-depth analysis of what the PMU of L2D_CACHE_WR counts on the Neoverse N2 server.

We refer to the SPE performance methodology whitepaper published by Arm for details on the content of this blog.

We discuss some of the challenges that we face when we are trying to implement the WebAssembly SIMD bitmask operations on the 64-bit Arm architecture.

This blog introduces how to profile firmware with Performance Monitor Unit (PMU) in Armv8-A CPU. It provides a reference implementation of the PMU library.

Views from the Arm technical leadership team that it believes that today, the cost implications of tightening C++ relaxed atomics outweigh its benefit.

This is the second and final part of the blog series on Dev Testing in .NET. In this part we look at further uses of SuperPMI and fuzzing with Fuzzlyn.

In part 1, we look at how .NET uses environment variables, some detailed IR dumps and SuperPMI.

The latest features and updates that have been added to Arm's A-Profile architecture in 2023.

This is the final part of the blog series on If Conversion in .NET. In this third post, we will look at some additional variations.

This blog series gives an overview of the recently added If Conversion pass, with part two looking at the the lowering phase.

This blog series gives an overview of the recently added If Conversion pass, with part one looking at the optimise bools optimisation.

Part 3. This blog introduces how to enable PMU feature in Armv8-A CPUs and provides an example of performance analysis workflow on real Armv8-A platform.

Part 2. This blog introduces how to enable PMU feature in Armv8-A CPUs and provides an example of performance analysis workflow on real Armv8-A platform.

This blog post introduces how to enable PMU feature in Armv8-A CPUs and provides an example of performance analysis workflow on real Armv8-A platform.

This blog describes how to add Arm Scalable Vector Extension (SVE) support to a SIMD library. It also introduces SVE features and programming tips.

A quick look at Neon intrinsics in Rust. This will explain the status of the intrinsics in the Rust compiler. We will also show how they differ from C.

With new open-source patches for the Realm Management Extension (RME) now available, this blog explores latest developments and techniques for confidential computing on Arm.

This blog introduces Arm optimization practices with two solid examples from Apache Arrow project.

This guest blog shows how 64-bit Neon technology can be used to improve performance in image processing applications.
