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

ARM architecture supplies the foundational design for processors and cores, being integrated into smartphones, micro‑computers, embedded devices, and even servers, and offers a common instruction set and programming model to ensure software interoperability across ARM devices.

The article highlights ARM's presence in high‑performance computing, noting that the Fugaku supercomputer, powered by an ARM‑based processor, achieved 415.5 PFLOPS on the Linpack benchmark and topped the HPCG test with 13.4 PFLOPS.

Cycle Models, generated directly from ArmRTL, preserve functional and cycle‑accurate behavior, enabling designers to evaluate ARM IP, make architectural decisions, and develop bare‑metal firmware before silicon is available.

ARM's business strategy focuses on maintaining market share in the long‑tail IP business, increasing royalty revenue per device, investing in new technologies such as GPUs and AI chips, and expanding beyond smartphones into smart automotive, robotics, AR, large‑scale cloud computing, and security solutions.

ARM China was established to address regulatory concerns after the acquisition, operating as an independent sales entity with pricing authority, continuing the IP licensing model, and potentially developing its own IP for global distribution.

The ARM Cortex family, based on ARMv7/v8 architectures, includes classic processors (Cortex‑A series), real‑time processors (Cortex‑R series) for automotive and imaging systems, and the Pelion IoT platform that provides device, connectivity, and data management services.

ARMv8‑A marks a major milestone by introducing a 64‑bit architecture while retaining backward compatibility with 32‑bit code, and the 2020 TechDay unveiled new CPU micro‑architectures, the Cortex‑A78 and Cortex‑X1, targeting high‑performance servers.

Mali‑G68, the first mid‑range GPU from ARM, sits between the Mali‑G50 and Mali‑G70 series, inheriting the architecture of Mali‑G78 but limited to six cores.
