Overview

What are Chiplets?

Chiplets are modular building blocks of a system-on-chip (SoC), enabling different subsystems—like compute, memory, and I/O—to be developed, optimized, and manufactured independently. Unlike monolithic chips, which are built as a single block, chiplets allow designers to mix and match best-in-class components, often using different process nodes. This modular approach improves yield, lowers development costs, and allows for faster, more scalable innovation—bringing greater flexibility to custom silicon design.

Future of Chiplets

What's Next for Chiplet Technology

The future of chiplets is defined by modularity, scalability, and accelerated innovation in silicon design. As compute demands grow more specialized, chiplets make it possible to combine best-in-class components—each optimized for a specific function—into flexible, high-performance systems. This approach reduces development time and cost while enabling greater customization across a wide range of markets. With growing ecosystem support and standardization, chiplets are paving the way for a more agile and collaborative era of semiconductor innovation.

Our Approach

Our Approach: Building Chiplets on Arm

Arm is uniquely positioned at the center of this transformation and diverse ecosystem, with a long-standing commitment to standardization and composability. Through investments in tools, system architecture, and open standards like AMBA, we’re helping to shape a flexible, multivendor chiplet marketplace that accelerates custom silicon design.

Industry Experimentation

 

We will enable partners to experiment with early chiplet designs, alongside a primarily monolithic marketplace.

Customized Collaboration

 

This enables multi-vendor systems across multiple dies (custom engagements and interfaces).

Chiplets Become Interchangeable

 

In time, we will see chiplets being used for systems not originally intended, thanks to standards that enable reuse.

Long-term Goal

 


Our vision is an 'Arm-based open chiplet marketplace', complete with composable and reusable solutions (eg. PCB-level integration).

Redefining the Chiplet Landscape with Arm

Unlocking the full potential of chiplet technology requires industry-wide collaboration, investment in standardization, and unified system-level capabilities to ensure a cohesive, reusable chiplet ecosystem.
