TIER IV, the original developer of the open-source autonomous driving software platform Autoware, has joined the Arm® Total Design for Physical AI ecosystem. Building on an existing technology relationship with Open AD Kit over several years, this strategic collaboration will be designed in such a way that it enhances Autoware’s flexibility and compatibility with Arm SoC and ECU computer architecture.
This technology collaboration effort offers a pre-validated way forward for semiconductor fabrication plants, tier-one suppliers, and OEMs in developing autonomous cars.
Fusing Open-Source Autonomy with Physical AI Infrastructure
The Arm Total Design for Physical AI program unifies hardware vendors, software developers, and system integrators to simplify the design and commercial deployment of intelligent edge systems operating in physical environments.
As an ecosystem partner, TIER IV will contribute its deep domain experience in full-stack open-source autonomous driving, edge AI optimization, and real-world system architecture. The integration aims to connect the global Autoware developer ecosystem directly with Arm‘s computing network, allowing developers to transition autonomous software pipelines from simulated environments onto production-grade vehicular hardware.

This architectural framework consists of an integration of the open-source software platform of TIER IV’s Autoware and Open AD Kit, which together provide an abstraction layer that is flexible enough for hardware and software. The framework functions effectively in the Arm Total Design of Physical AI computing ecosystem where software performance is optimized over Arm SoCs, domain controller, and ECUs on board. Designed with the intention of reducing barriers to integration, this technical stack helps to achieve faster time to market in automotive solutions.
Expanding the Open AD Kit Framework
The agreement builds on existing development efforts between TIER IV and Arm centered around Open AD Kit-an open hardware-abstraction framework created within the Autoware Foundation to standardize how autonomous driving software interfaces with underlying silicon architectures.
The joint framework was highlighted at CES 2026, demonstrating live Autoware workloads executing on Arm-based computing platforms. Moving forward, TIER IV plans to deliver pre-configured, optimized Autoware software stacks tailored for Arm-based SoCs, helping automotive engineering teams reduce cycle times from initial prototyping to mass-production verification.
“Making autonomous driving accessible requires more than open-source software. Developers also need a practical path to bring that software onto the computing platforms that power real-world systems,” said Shinpei Kato, founder and CEO of TIER IV. “Our collaboration with Arm through Open AD Kit has helped bridge that gap. By joining Arm Total Design for Physical AI, we look forward to extending this work with a broader network of partners and accelerating the democratization of autonomous driving.”
“The path to scalable autonomy depends on making it easier for software and hardware to evolve together,” said Dermot O’Driscoll, vice president of go-to-market, Physical AI, Arm. “Our work with TIER IV through Open AD Kit has already demonstrated that potential, and Arm Total Design for Physical AI gives us an opportunity to extend that collaboration across a much broader ecosystem.”
Democratizing Next-Generation Autonomous Mobility
Through its participation in the Arm Total Design ecosystem and ongoing developments within Open AD Kit, TIER IV aims to reduce technical friction for developers globally. By offering validated reference designs across a diverse range of Arm-based silicon platforms, the alliance supports the broader democratization of safe, scalable, and cost-effective autonomous mobility systems.
