The Arm architecture is one of the most popular processor architectures in the world today, with several billion Arm-based devices shipped every year. There are three architecture profiles: A, R and M.
Arm CPU Architecture – Arm®
The Arm central processor unit (CPU) architecture comes in three varieties: A-Profile for rich applications (latest: Armv9-A), R-Profile for Real-time, and M-Profile for microcontrollers. Armv9 will deliver new security features including confidential compute and a …

Micro-architecture includes things like: Pipeline length and layout; Number and sizes of caches; Cycle counts for individual instructions; Which optional features are implemented; For example, Cortex-A53 and Cortex-A72 are both implementations of the Armv8-A architecture.
A walk through of the Microarchitectural improvements ... - Arm …
At ARM we are focused on delivering IP that enables the most efficient computing and the Cortex-A72 micro-architecture is the result of several enhancements that increase performance while simultaneously decreasing power.
First Armv9 Cortex CPUs for Consumer Compute - Arm Community
2021年5月25日 · For all three Armv9 CPUs, we are building on three distinct micro-architecture paths that are unmatched in the industry. Essentially this means we are building the right CPU for the right workload. The Cortex-X series is designed to maximize performance on single-threaded and “bursty” workloads.
Neoverse V1 Performance Analysis whitepaper - Arm Community
Familiarizing yourself with the Arm Neoverse microarchitecture, including its complex pipelines and multi-level memory hierarchy, can be helpful in this process. As the Neoverse cores provide over 100 hardware counters to select from, it is important to prioritize which events to focus on.
Cortex-X: The X-factor in Arm’s CPU Performance
2021年3月24日 · Our planning and discussions with partners revealed that we need a new CPU option built on a scale and scope never seen before. Arm's technical talent responded with not only a novel microarchitecture, but also a culture shift in how we design CPUs.
Documentation – Arm Developer
Neoverse N2 supports the following microarchitecture exploration metric groups that can be used for Stage 2 analysis. The metric groups here support further analysis of the bottlenecking CPU resources following the Stage 1 analysis hotspot.
Arm Cortex-X4 advances frontiers of CPU performance
2023年5月29日 · This best-in-class performance is possible due to a step increase in the instruction bandwidth in the front-end microarchitecture. Alongside performance, Cortex-X4 is the most efficient Cortex-X CPU core ever built, with 40 percent better power efficiency ² .
Microprocessor Cores and Processor Technology – Arm®
Targeted microarchitecture optimizations for 20% power efficiency improvements. Consistent performance gains to match Cortex-X1, Arm’s first-generation Cortex-X CPU.
