Overview of ARM Architecture, Business Strategy, and Recent Product Developments

Today we share ARM-related knowledge covering five parts: a historical interpretation of ARM, an introduction to its business, expansion into AIoT, new business models and ecosystem, ARM architecture and new products, and the challenges it faces.

ARM architecture provides the foundation for processor and core design, being integrated into smartphones, micro‑computers, embedded devices, and even servers as system‑on‑chip (SoC) solutions.

The architecture offers a common instruction set and programming model for software developers, ensuring interoperability across different ARM implementations so that software can run on various ARM devices.

Cycle Models, compiled directly from Arm RTL, retain full functionality and precise timing, enabling confident IP selection, architectural decisions, system performance optimization, and bare‑metal firmware development before silicon is available.

ARM's business strategy focuses on maintaining market share in long‑tail IP, increasing per‑device royalty revenue by developing more advanced IP, investing in new technologies such as GPUs and AI chips, and expanding into markets beyond smartphones, including IP services.

ARM China, established to reassure regulators about independence after acquisition, operates as a sales subsidiary with independent pricing and decision‑making, continues the IP licensing model, and may eventually develop its own IP products for global distribution.

The ARM architecture is one of the most popular processor architectures worldwide, shipping billions of devices annually, with three profile configurations: A, R, and M.

Armv8‑A marks a major milestone as a 64‑bit architecture that still supports 32‑bit execution for backward compatibility with older software (e.g., v7, v6, v5).

At ARM 2020 TechDay, a new CPU micro‑architecture was announced along with Cortex‑A78 and Cortex‑X1 products, representing flagship performance designs aimed at the server market and reflecting significant shifts in ARM's business model.

The Mali‑G68 is ARM's first mid‑range GPU, positioned between the Mali‑G70 and Mali‑G50 series, inheriting the architecture and features of the Mali‑G78 but limited to a maximum of six cores.

ARM identifies future strategic opportunities in smart devices, autonomous systems, augmented reality, large‑scale cloud computing, connectivity, and the associated security and privacy requirements.
